Use of Wharton Jelly in Diabetic Nephropathy
- Conditions
- Diabetic Nephropathies
- Interventions
- Biological: Wharton Jelly Mesenchymal stem cells
- Registration Number
- NCT03288571
- Lead Sponsor
- Sophia Al-Adwan
- Brief Summary
Wharton Jelly derived Mesenchymal stem cells will be injected in the renal parenchyma of patients with Diabetic Nephropathy
- Detailed Description
Mesenchymal stem cells (MSCs) are to be isolated from Umbilical cord Wharton's Jelly obtained after normal full term delivery.
Samples will be tested for any bacterial or fungal growth as well as endotoxin and mycoplasma. The specific markers for MSCs identification will be analyzed by flow cytometry.
Cell suspension will then be injected in the renal parenchyma of patients diagnosed with diabetic nephropathy.
