Abstract Introduction Critical limb ischemia (CLI) is the most advanced form of peripheral arterial disease (PAD) characterized by ischemic rest pain and non-healing ulcers. Currently, the standard therapy for CLI is the surgical reconstruction and endovascular therapy or limb amputation for patients with no treatment options. Neovasculogenesis induced by mesenchymal stem cells (MSCs) therapy is a promising approach to improve CLI. Owing to their angiogenic and immunomodulatory potential, MSCs are perfect candidates for the treatment of CLI. The purpose of this study was to determine and compare the in vitro and in vivo effects of allogeneic bone marrow mesenchymal stem cells (BM-MSCs) and adipose tissue mesenchymal stem cells (AT-MSCs) on CLI treatment. Methods For the first step, BM-MSCs and AT-MSCs were isolated and characterized for the characteristic MSC phenotypes. Then, femoral artery ligation and total excision of the femoral artery were performed on C57BL/6 mice to create a CLI model. The cells were evaluated for their in vitro and in vivo biological characteristics for CLI cell therapy. In order to determine these characteristics, the following tests were performed: morphology, flow cytometry, differentiation to osteocyte and adipocyte, wound healing assay, and behavioral tests including Tarlov, Ischemia, Modified ischemia, Function and the grade of limb necrosis scores, donor cell survival assay, and histological analysis. Results Our cellular and functional tests indicated that during 28 days after cell transplantation, BM-MSCs had a great effect on endothelial cell migration, muscle restructure, functional improvements, and neovascularization in ischemic tissues compared with AT-MSCs and control groups. Conclusions Allogeneic BM-MSC transplantation resulted in a more effective recovery from critical limb ischemia compared to AT-MSCs transplantation. In fact, BM-MSC transplantation could be considered as a promising therapy for diseases with insufficient angiogenesis including hindlimb ischemia.

Critical limb ischemia (CLI) often results in amputation, but autologous cellular therapy using bone marrow-derived mesenchymal stem cells (MSCs) may be able to prevent this outcome. However, the quality of MSCs in the CLI population is not clear. Amputated CLI limbs contain reservoirs of MSCs that can be used to characterize their stromal capacity. We hypothesize that MSC stromal capacity is relatively preserved in ischemic limbs compared to ones from healthy donors. Methods Healthy donor MSCs (hdMSCs, n=2) and ischemic MSCs (iMSCs, n=3) from amputated limbs of non-diabetic CLI patients were cultured. Human microdermal ECs were commercially obtained. Co-culture pellets (1:1 ratio) of hdMSC:EC, iMSC:EC, and EC alone were formed and cultured in 3-D fibrin hydrogels in EC growth media. Images of the pellets and invasion areas were captured up to 5 days. The invasion area was quantified as the difference between the total and pellet area normalized to initial pellet area. Experiments were performed in quadruplicates and co-culture experiments were duplicated. Results iMSC:EC co-culture provided similar stromal support as the healthy donor cohort. Both MSC groups were significantly greater than the ECs alone following day 2 (see figure, *P<0.0005, ANOVA). Both MSC groups also exhibited significant increase in invasion area with time (P<0.01) while the ECs did not (P>0.5). Conclusion This is the first study to demonstrate that iMSCs provide similar stromal support to ECs as healthy hdMSCs, thus iMSCs may be of sufficient quality for use in autologous therapy. We are currently quantifying secretome expressions of the iMSCs to provide insights into mechanisms of the stromal support.
