Regenerative Medicine for Type 1 diabetes: Research & Application

Imagine diabetes treatment that goes far beyond replacing insulin and focuses on the restoration of pancreatic beta cell function and immunomodulation.While insulin therapy remains the cornerstone of type 1 diabetes management, it only combats the symptoms. This has fueled the need for regenerative medicine that can regenerate and repair the lost/damaged to the pancreatic cells. Regenerative Medicine for Type 1 Diabetes targets the repair and regeneration of the damaged pancreatic beta cells and regulates the immune response. Currently, the field continues to evolve and isn’t yet recommended as a standalone therapy. Yet, early clinical trials have shown promising evidence to make intrinsic changes. The following article uncovers science, current evidence, benefits, and the future of stem cell therapy for diabetes management.

Ask The Expert

What is Type 1 Diabetes?

Type 1 Diabetes mellitus (T1DM) is a metabolic autoimmune condition where an individual’s own immune system attacks pancreatic beta cells and restricts them from making insulin. The body does not make adequate insulin to absorb glucose and regulate blood sugar levels. The condition appears at an early life stage (children, teens or younger adults) and is also known as juvenile or insulin-dependent diabetes.

The accurate cause of juvenile diabetes is not completely understood. Till date, scientists have unveiled the role of genetic factors or exposure to certain environmental toxins. They can potentially make pancreatic beta cells susceptible to an immune response, leading to their destruction.

The Common Symptoms of T1DM Among Children Include:

Fatigue
Excessive thirst
Unexplained weight loss
Blurred vision
Slow healing of cuts/sores
Excessive hunger
Frequent urination, bed wetting, etc.

The above symptoms can begin as mild and worsen over days.

What are the Treatments Available for T1DM?

Endocrinologists mark T1DM as a self-managed disease. The patient and their caregivers need to make constant decisions to maintain overall health. Conventional treatment options involve:

Insulin Therapy

Based on the disease severity, the individual’s need for insulin therapy is recommended
Basal insulin or long-acting insulin is recommended
Administration is prescribed distinctly, including multiple daily injections, pen, insulin pump, or inhalation of rapid-acting insulin

Blood Glucose Monitoring

Continuous glucose monitoring (CGM) or a blood glucose meter is prescribed
Constant monitoring of glucose levels in a specific time range
CGMs and glucose pumps can work in a constant loop

Education

Patient and primary caregiver education plays a crucial role
Keeping up with nutritional needs and regular physical activities is crucial
Detection of low/high blood sugar in real time and immediate action
Knowledge of diabetes management in school or work

*NOTE: The above treatment for T1DM targets symptom management rather than reversing the damage.

How Regenerative Medicine for T1DM Works?

Regenerative medicine for type 1 diabetes harnesses the power of stem cells to generate insulin-producing islet cells. The treatment intends to reduce insulin dependency and deliver long-term benefits significantly. Researchers have widely explored the potential of mesenchymal stem cells (MSCs) for treating T1DM. MSCs are sourced from bone marrow, umbilical cord blood/tissue, or adipose tissues. Besides, MSCs have a superior biosafety profile inside the human body and possess the least risk of tumourigenicity.

Diabetes Stem Cell Treatment intends to regenerate and repair beta islet cells, reduce chronic inflammation, and modulate immune response.

How Does Stem Cells Work in Type 1 Diabetes?

Stem Cells for Diabetes Management Undertake the Following Mechanism of Action:

Regeneration

MSCs secrete various growth factors and cytokines (secretome) that stimulate the tissue repair mechanism
They boost the regeneration of the beta islet cells in the pancreas
MSCs release angiogenic factors like VEGF, FGF, etc., that promote angiogenesis and the pancreatic blood supply

Immunomodulation

MSCs interact with immune cells and regulate aggressive immune responses
They restrict misguided autoimmune attack and preserve insulin-producing cells
MSCs release anti-inflammatory molecules that neutralize pro-inflammatory responses
It creates a supportive microenvironment for the survival of pancreatic cells

Manage Metabolic Complication

Clinical evidence revealed better blood glucose management among patients receiving treatment with MSCs
Lower HbA1c level, reduced insulin dependency
MSCs displayed neurotrophic and pro-angiogenic effects, supporting damaged nerve repair and improving blood circulation

How Are Different Countries Advancing Regenerative Care in T1DM?

Global Case Studies evidence for Regenerative medicine for type 1 diabetes includes:

United States

Global leader in Diabetes Stem Cell Treatment research
Clinical program launched by Zimislecel reported improved C-peptide production, improved glycemic control and reduced insulin dependency
Researchers are focusing on developing encapsulation technology (to protect transplanted beta cells from immune attack). Potentially reduces the need for lifelong immunosuppression
Currently, FDA-approved clinical trials are ongoing. No therapy is FDA-approved

Japan

Induced pluripotent stem cells (iPSCs) are widely explored in Japan
Kyoto University project and various commercial clinics are running early-stage clinical trials with iPSCs for the regeneration of beta islet cells
No iPSCs therapy is yet approved

China

Widely using MSCs sourced from umbilical cord or adipose tissue
Current evidence suggests preservation of pancreatic beta cell function
Improved C-peptide secretion, reduced inflammatory responses
Lower insulin dosage requirement among the treated patients
Widely explored as a combinational approach, and available through regulated research

India

Autologous and allogeneic MSCs are widely explored as adjunctive therapy
Preliminary clinical outcome reported reduced insulin dependency and improved glycemic control
Currently, stem cell therapy isn’t approved as standard treatment. It is combined with conventional treatment as supportive option
Patients seeking Stem Cell Therapy for Diabetes in Delhi or other major cities must ensure they follow the regulatory guidelines
National Guidelines for Stem Cell Research (NGSCR), in India are listed by ICMR and DBT

*NOTE: Globally, Regenerative medicine for type 1 diabetes is not approved as standard treatment. Despite the advancement, stem cells for diabetes treatment are viewed as emerging therapeutic options. Currently, clinical applications are highly regulated and come as combinational or supportive options.

Who are the Suitable Candidates?

Selection of Suitable Candidates is Crucial for the Success of Regenerative Medicine. This Includes:

Individuals experiencing recurrent life-threatening hypoglycemic events
Candidates with immunosuppression tolerance
Individuals with overall good health, no active infection or malignancies
Maintain a stable body weight, follow strict dietary regulations

What are the Key Considerations?

Individuals Opting for Diabetes Stem Cell Treatment Must Consider:

Consulting experienced clinicians and a renowned clinic for delivering stem cell therapy
Superior clinical-grade stem cells are used for optimal outcomes
