Human iPSC for Repair of Vasodegenerative Vessels in Diabetic Retinopathy
Source: ClinicalTrials.gov · Last updated 26 Oct 2026
Brief summary (registry, in English)
This study proposes to carefully examine the hypothesis that human inducible pluripotent stem cells (iPSCs) can be effectively employed as a future therapeutic option for individuals with diabetic retinopathy and macular ischemia. iPSCs will be generated from the peripheral blood cells of subjects with diabetes and age matched controls. The human iPSC cells will be used to generate mesoderm cells for injection into the vitreous cavity of diabetic rodents and primate eyes. The ability of mesoderm cells to generate endothelial cells and pericytes in areas of degenerated capillaries will be examined. The human iPSCs will also be used to generate hematopoietic CD34+CD45+ cells. The combination of CD34+CD45+ cells derived from iPSCs and iPSC derived mesoderm will be examined in combination for their potentially beneficial effect to enhance the vessel formation.

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.
Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- We will apply the following exclusion criteria: a) evidence of ongoing acute or chronic infection (HIV, Hepatitis B or C, tuberculosis); b) ongoing malignancy; c) cerebral vascular accident or cerebral vascular procedure; d) current pregnancy; e) history of organ transplantation; f) presence of a graft (to avoid any effect of the graft on inflammatory parameters; and g) patients with anemia. Subjects with AMD, glaucoma, uveitis, known hereditary degenerations or other significant ocular complications other than diabetic retinopathy will be excluded.
Who the study is looking for
- Any man or woman between the ages of 21- 98 years of age will be eligible to participate. To participate in the study as a study subject we will require: a) the subject must either carry the diagnosis of diabetes or be a healthy aged control and b) the patient be willing and have the ability to cooperate with the eye exam and skin punch biopsy protocol.
Age in the registry: 21 years to 98 years · Sex: All · Accepts healthy volunteers
