Stem Cells For Diabetes: The Science Behind New Hope

Understanding Diabetes: A Global and Indian Health Challenge

From bustling cities to rural communes- Diabetes has quietly become a pressing health challenge that requires new solutions. 

Diabetes or hyperglycemia, is a chronic metabolic disorder that is caused by high levels of glucose in the bloodstream. As per the World Health Organisation, approximately 830 million individuals in 2022 were affected with diabetes [1]. Severe Diabetes comes with serious consequences like blindness, cardiovascular disease, hypertension, kidney failure, and lower limb amputation. In India, approximately 89.9 million individuals between 20 and 79 years were affected by Diabetes. The cases are estimated to increase to 156.7 million in 2050 [2].  

The current treatment regimen focuses on diabetes symptom management. However,  a complete cure is a big challenge. Stem Cells for Diabetes are emerging regenerative medicine for diabetes treatment that enables cellular regeneration.

Disease Pathophysiology and Subtypes

Diabetes Mellitus refers to a group of diseases where the body is unable to produce or utilize insulin. It can be majorly subcategorized as:

• Type 1 Diabetes Mellitus (T1DM) juvenile Diabetes autoimmune subtype where the body’s immune system targets the pancreatic beta cell (responsible for producing insulin).  
• Type 2 Diabetes Mellitus (T2DM), the most common subtype, is characterized by the body’s inability to use insulin, which leads to sugar buildup in the blood stream. 
• Gestational Diabetes occurs during pregnancy and resolves after the child’s birth. 

Among the major subtypes, T1DM and T2DM are of utmost importance. Currently, conventional diabetes treatment involves:

• Medications
• Insulin Therapy
• Dietary Management
• Physical Activities

However, these treatments are subjected to intense challenges. This includes poor patient adherence, weight gain, ineffective glucose monitoring, hypoglycemia, etc.

To overcome such limitations, the current research is focused on developing curative solutions by using stem cells for Diabetes. 

Diabetes Treatment-Stem Cell Therapy

Stem cells for Diabetes have emerged as a promising investigational approach to overcome conventional treatment limitations. Researchers highlighted the role of mesenchymal stem cells (MSCs) in addressing the root cause of T1DM and T2DM. The core mechanism of action involves:

• Pancreatic Beta-Cells Regeneration: MSCs secrete various secretome (growth factors and cytokines) that stimulate tissue repair mechanisms. These factors release facilitates repair and regeneration of pancreatic beta cells that are responsible for insulin production. MSCs ameliorate hyperglycemia but create a supportive microenvironment for stem cell regeneration and survival. 
• Immunomodulation: MSCs potentially interact with immune cells and release natural signals to reduce antagonist signals. T1DM is subjected to an unguided immune attack that can be reduced by stem cell therapy. While in T2DM, stem cells improve chronic inflammation and promotes healthier immune balance
• Altering Metabolic Control: stem cells for Diabetes promote cellular repair and modulates the immune system for systemic benefits. Clinical studies reflected better blood sugar control among patients receiving MSCs- lower HbA1c level, need less insulin to manage Diabetes by 50%, some became insulin-independant

What are the Major Research Outcomes?

MSC treatments have demonstrated various essential outcomes. This includes:

• Improved Blood Glucose Control: the patient showed a drop in HbA1c from baseline.
• Reduced Insulin Dependency: some patients become less dependent on insulin, while some T1DM patients become insulin-dependent-free after a specific treatment period.
• Improved Beta-Cell Function: Increase in C-peptides, a biomarker of insulin production
• Safety and Tolerability: MSCs administration showed negligible side effects and good tolerance. Autologous transaction eliminates the risk of rejection.

 

What Does Global Landscape Say?

Diabetes Stem Cell Treatment globally has shown promising outcomes. Some critical cases include: 

Study 1:

• Deng Hongkui from Peking University used cells from three patients with T1DM
• Chemically reprogrammed into pluripotent stem cells, created 3D clusters of insulin-producing islet cells
• 1.5 million islet cells transplanted in 25-old women’s abdominal muscle with T1DM
• Obtained insulin independence 75-days post-transplantation, blood sugar remained in control (ChiCTR2300072200) [3]

Study 2:

• Clinical Trial with 21 patients with T1DM
• Most patients became insulin-free for three and a half years; one patient did not require insulin support for 8 years [3]

Study 3:

• Research at the University of Florida used preserved cord blood cells for treating T1DM.
• Used thymic regulatory T cells (tTreg cells)- white blood cells, prevents autoimmune response
• Cultured 1.26 billion Treg cells, introduced in the patient
• Replenished low tTreg cells count, replaced damaged or bad tTreg with new cells,
• Treatment renewal possible with insulin-dependency reappearance [3]

Study 4:

• Dr Yong Zhao used cord blood cells to develop a stem cell educator (SCE)
• Re-reducate lymphocytes and restricted autoimmune response
• SCE regulated patient’s bloodstream in a closed-loop system, separates mononuclear cells from the whole body
• Does not introduce new cells in the patient, trail focus on re-education purposes [3]

Study 5:

• Dr. Yin Hao used the patient’s own endoderm stem cells (EnSCs) for a 59-year-old male patient with T2DM for 25 years.
• EnSCs differentiate into functional pancreatic beta islet cells
• After autologous transplantation, the patient gained insulin independence after 11 weeks of post-transplantation [4]

What is Happening with Stem Cell Treatment for Diabetes in India?

India is actively thriving in Stem Cell Therapy for Diabetes. The successful outcome includes:   

Study 1:

• Dr Sagar Jawale used the patient’s own fat cells from a T1DM patient
• Cultured stem cells and introduced 5-year old child with T1DM patient
• After 8 weeks of therapy, significant control in glycemic index
• Total Treatment cost  Rs 75,000- Rs 90,000

Study 2:

• Dr Sagar Jawale, in collaboration with Dr. Kiran Patil, infused stem cells into the pancreas
• Cells harvested from the patient’s own bone marrow in a 20-year-old patient
• Blood sugar level steadily dropped upto 2 years after single transplantation
• Treatment cost Rs 90,000

*NOTE: Both cases were successful with a significant reduction in treatment cost. The strategy of using patients’ own fat/adipose cells significantly reduced cost, with no compromise in quality or patient care.

Future Directions in Stem Cell–Based Diabetes Therapy

• Advances in beta-cell replacement strategies
• Combination therapies promote treatment efficacy
• A crucial aspect in developing personalized regenerative medicine
• A large-scale clinical trial study for determining long-term safety is necessary.
