Development of Cutaneous Wound in Diabetic Immunocompromised Mice and Use of Dental Pulp-Derived Stem Cell Product for Healing.

Chronic nonhealing wounds impact nearly 15% of Medicare beneficiaries (8.2 million) in the United States costing $28-$32 billion annually. Despite advancement in wound management, approximately 8% of diabetic Medicare beneficiaries have a foot ulcer and 1.8% will have an amputation. The development of a regenerative approach is warranted to save these before-mentioned amputations. To this extent, herein, we describe the detailed methods in generating a type 1 diabetes mellitus (T1DM) condition in immunocompromised mice, inducing cutaneous wound, and application of dental pulp stem cell-derived secretory products for therapeutic assessment. This model helps in evaluating the efficacy of stem cell-based therapy and helps with the investigation of involved mechanisms in impaired cutaneous wound healing caused by hyperglycemic stress due to type 1 diabetes.
