Therefore, in this study, we have first generated MSCs and endothelial progenitor cells (EPC) from mice bone marrow by in house optimized protocol and then 3-D co-cultured them with mice islets. Secretion of in the culture supernatant suggested the pro-angiogenic nature of 3D cultured mice islets. After 5 days post-tx of these pro-angiogenic islets in the omental pouch of syngeneic mice led to: 1) restoration of normoglycemia, 2) secretion of mouse C-peptide and 3) induction of angiogenic factors after 3 days of post-tx. The induction of angiogenic factors was done by RT-qPCR of omental biopsies. Importantly, pro-angiogenic islet recipient mice also demonstrated the clearance of glucose within 75 min, reflecting their efficient function and engraftment. Our results highlights needs of 3-D co-culture islets for superior quality post-tx islet vasculature and better engraftment â€\" crux to improvise the challenges associated with post-tx islet vascularization and functions.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2023,"id":392895,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9553,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":344186,"name":"Afsar R.
