In the recent stem cell summit, we had so many strategies to improve the quality of stem cell transplants and make them successful. One of such strategies undertaken in the January Summit, held in Florida raises a concern over the performance of CD19 and finds pathways to improve its efficacy to target solid tumors.

The success of clinical studies on the efficacy of modified T cells garnered our hopes in the development of novel therapeutic treatments. We have witnessed that modification of chimeric antigen receptors (CARs) have been able to defy the cytotoxicity of tumors in many clinical studies. Engineered CD19 CAR-T cells being active in inducing anti-inflammatory immunity against B-cells malignancies, these cells are participating in the development of cancer adoptive immunotherapy.

However, the hurdle in its way seems to be its ineffectiveness to combat solid tumors. We can find several factors that work against various approaches of these modified T-cells. The first one being the neoplasm activity of the microenvironment, which does not allow CAR-T cells to survive and reach the tumor surface. The host’s defensive mechanism becomes ineffective due to the useless anergic status developing from the ambiguous interactive communication amongst tumor components, stromal and immune cells.

Amidst these confusions, what pathways we should take to improve the performance of CD19 CAR-T cells? Or Should we look beyond some other immunotherapy to treat solid tumors?

Anti-tumor efficacy of anti CD19 CAR-T cells has been expressed in children and adults through many clinical studies. T-cells can express its anti-immunotherapy properties against a series of B-cell acute lymphoblastic leukemia and other B-cell malignancies. We have two anti-cancer immunotherapies infused with anti-CD19 CAR-T cells named YESCARTA and KYMRIAH. Both these drugs are useful in suppressing B-cell expressions.

While this antigen CD19 CAR-T cell is capable of treating many B-cell malignancies, it is ineffective to even target solid tumor cells. Why so?

Its poor efficacy against malignant epithelial cells is due to the lack of capacity to target specific antigens in the microenvironment. Its inability to target active splice variant of epidermal growth factor receptor (EGFR), causes the growth of solid tumors and creates a hostile nature for its survival.

While this immunotherapy fails to provide a positive result for the patients with solid tumors, other antigens like anti GD-2 CAR-T cells have shown some promises to treat different malignant conditions in clinical trials. Therefore, we can demand more clinical trials which can bring forth the introduction of anti-cancer immunotherapy using antigens.

By using IL-2 support and increasing the number of cells for the ACT in melanoma, we can achieve a positive result for patients with solid tumors. Simultaneously, the physical barriers created by epithelial and mesenchymal cells need to be restricted to prevent ill effects of the cytotoxic functions of the solid tumors. And to effectively increase its efficacy against solid tumors, its persistence, eruption in the environment and tumor homing should be increased.

At the same time, if this antigen underperforms despite some changes, we should look beyond this. A recent study showed that BCMA targeted CAR-T cells can effectively perform on tumor-specific cells to stop further spread of the diseases. Many clinical trials have shown promises that this antigen could provide adequate relief from multiple myeloma.

So, we can rest assured that clinical studies and research could bring us effective CAR-T cells based immunotherapy in order to combat multiple malignancies and myeloma in future.

Bare Lymphocyte Syndrome or most popularly known as MHC Class II deficiency is a rare form of immunodeficiency disease. Children are at high risk as the disorder leaves its impact mostly on them. The disease may attack the patients when there is either deficiency of HLA Class I or Class II antigens on the cell surface.The allogeneic stem cell transplant is the only curative treatment options for this immunodeficiency disorder.

The occurrence of the disease may defer your body from developing responsible genes through chromosome 6. It hinders antibody from forming and restricts the cells from responding to the specific antigens. It is evident to experience more physical complications in the respiratory and digestive tract. And as a result, your normal life finds it difficulty in breathing and digesting food.

More severe complications are there for you when you develop the immunodeficiency disease. You are likely to develop hypogammaglobulinemia, which results in recurrent viral infections caused by parasites and bacteria.

You could find a treatment solution for this disease from allogeneic or HLA matched stem cell transplant. However, the survival rate of the patients is highly dependent on the donor cell types.  HLA matched donor transplant improves the survival quality, while the unmatched donor cell transplants offer you 50% of survival success.

The relief from the debilitating complications of the disease finds its way through a successful allogeneic stem cell transplant. On failure of the transplant, most children may succumb to infections in their first phase of life.

Other than this, the alternative donor transplant does not suit the process of the Stem cell transplant. Similarly, other types of immunodeficiency diseases do not benefit from this process as well. Till date, the stem cell transplant using alternative donors increases the chances of Graft-versus-host-disease reactions, incessant graft rejections, and even mortality due to infections.

If you look at the finding of a study carried out on the 16 diseased children, you will have a clear idea about the efficacy of the SCT.

In 1990, 16 affected children were ready for the transplant with the samples. The specimens were derived from HLA unrelated family member, HLA matched adult donor and mismatched cord blood donor. These patients were under treatment in four different medical centers.

None of the patients had experienced chronic GVHD after the first transplant. However, five patients who underwent the second phase of transplant experienced graft failure. And six patients amongst them developed acute GVHD complications. In spite of that, Stem cell transplant seems to offer the best survival results at 69% of success rate for the children.

Another process for the treatment of bare lymphocyte syndrome is utero stem cell transplant. Many fetal disorders or immunodeficiency disorders like BLS gain good benefits from the utero stem cell transplant.

The possible treatment for BLS depends on the maternal T-Cell to be injected intravascularly. With the use of the maternal cells, the results achieve the highest chimerism levels. The robustness of the transplant remains stable for a period of two years with no traces of GVHD. This apart, the utero stem cell transplantation offers many curative treatments for dreadful diseases.

This therapy also reduces the relapse complications caused due to GVHD. Simultaneously, the donor cells receive a better environment to develop in the host fetal cells.

So, we can expect more of such therapies to relieve the health compilations of BLS at the earliest soon after the transplant takes its course.

The stem cells’ capability of self-renewal and differentiation has made it easier for medical persons, and clinical professionals to bring about different treatment options for many inexorable ailments. And this time, the magic of stem cells is weaving hopes for the patients suffering from the kidney diseases.

In a major breakthrough, the scientists at the University of Manchester have developed a functioning mini kidney. They developed it using stem cells within a living organism. It is exciting for the patients suffering the renal disease. The mini kidneys are capable of producing urine and acting as similar to the human kidneys. This is a big milestone in the treatment of kidney diseases. And that's why they could aid in multiplying the future treatment scopes for the patients one day.

A large number of populations is suffering from the kidney ailments. The mortality rate of the kidney patients is reaching an unprecedented number every year. Due to the chronic kidney failure, the kidney cannot produce urine. When the disease worsens, the kidneys fail to filter excess wastes and excrete fluids out of the body. As a result, at the advanced age, the wastes build up in the system and impair the kidney functions. The impaired kidneys impact the normal functioning of urine, and advocates for relief. To relieve this problem, patients have to undergo dialysis.

According to the study, around two million people opt for kidney transplantation or dialysis. But, most patients cannot afford these treatments.

The mini-kidneys developed with the stem cells are raising a silver lining for the patients with kidney dysfunctions.

The embryonic stem cells were the key elements to develop the kidney glomeruli in the living organism. Scientists fragmented these cells into different microscopic kidney tissues. And they used cultural dishes to grow them. The pieces were mixed with a gel-like substance that functioned as connective tissues. And the clump was then injected under the skin of mice. After three months, the functional tissues of the kidney- nephrons had developed.

The discovery has seen the wonders of the medical sciences for the first time. The kidney of the mouse or the nephrons included all the major parts as similar as the human nephrons. The experimental mice’s nephrons comprised distal tubules, proximal tubules, Bowman’s capsules, and Loop of Henle. To nurture the new formation of the kidneys, minute blood vessels found in the human body developed as well.

The kidneys of human have a large artery to flow the blood to the kidney. But, the newly developed functioning mini-kidneys in mice miss this feature. This is a major hurdle to bring about the true medical benefits to the patients with kidney ailments.

A fluorescent protein called dextran is capable of straining urine from the blood during the glomerular filtration process. So, scientists used dextran in the mice to examine the functionality of filtration and excretion of urine.

When the scientists tracked dextran, they saw that it was able to filtrate urine and excrete it.

So, there is no doubt about the new structures’ capability of filtration and excretion like kidney cells. However, it is still unclear how effectively the new structures function in the living organism.

Still, it leads to a hope to create more advanced treatments using the pluripotent stem cells.

Humans have innumerable glomeruli in their kidneys. And, this new structure has breathed a life through a few hundred glomeruli. Of course, they showed a sign of hopes for the future treatments in kidney ailments. And the further development and research using this technique may advance the existing treatment options for kidney diseases.

Why Do We Lose Our Hair

The human head has estimated 100,000 to 150,000 strands of hair. We tend to lose about 40 to 100 strands each day for a normal reason which are replaced back to their follicles by a new one. Unlike general causes, hair loss or alopecia is likely to occur due to genetic reasons. This apart, another factor triggers the loss of hair rapidly, such as chemotherapy, stress, injuries, and hormonal imbalance. Sometimes, being too much experimented with our own hair like coloring, bleaching, and straightening adds to the hair troubles. stem cell hair transplant therapy, stem cell therapy for baldness.

And when we reach 50, the pattern of baldness becomes apparent. This typical hair loss problem hits almost every person regardless of their gender. Different types of hair transplant surgeries have been in use for many times now. During such treatment procedures, skin with hair follicles is removed from the area where the hair is present and replaced onto the area where it is not present. But, it is seen that the result is not permanent if not proper care is taken. However, the regeneration of human hair is possible with stem cell therapy, which gives a permanent result.

The Science Behind Hair Loss

According to the study published in Nature Cell Biology, human follicles are able to grow hair throughout a person’s lifetime since it is infused with undying stem cells. These hair follicles come out of their inactivation period when a new hair cycle arrives, and trigger the growth of new hair. The period of inactivation is regulated by different factors and when it fails to be activated, the hair loss occurs.

How Can Stem Cell Therapy Be Used to Regrow Hair?

It all depends on the metabolism of the hair follicle stem cell. Hair cellular metabolism depends on the bloodstream to get glucose. And gradually, glucose is processed into a metabolite known as pyruvate. The cellular stem either processes pyruvate to make energy or change it to lactate. Further research shows that influencing the lactate could result in regeneration of the hair cycle. The research has been carried out on the mice in the lab at the University of Utah. And now, it is proved that the hair follicle stem cell could be inactivated with the blockage in the production of lactate, and the same could be activated with the removal of the blockage. So, the activation of hair follicle stem cell leads to the new hair cycle and thus results in the growth of hair. Another study in recent times proves that stem cells of the human embryo and fetal tissue can be used to create dermal papilla cells so as to form follicles and promote hair growth.

So, rest assured as gone are the days when you have to compromise with your bald look because there is sunshine right before your eyes.
