Mesenchymal stem cells (MSCs) hold great promise for therapeutic application in non-healing ulcers and tissue regeneration because of their multi-lineage differentiation potential. MSCs delivered may migrate to the sites of injury and improve wound healing by stimulating angiogenesis and promoting revascularization. The incidence of type 2 diabetes mellitus (T2DM) is increasing worldwide. It is associated with peripheral neuropathy and peripheral arterial occlusive disease (PAOD), which predispose patients to develop non-healing foot ulcers following minor trauma. A high rate of amputation exists among diabetic patients due to non-healing foot ulcers, which are a significant burden for the society despite new therapeutic protocols developed. In recent years, stem cell transplantation has been considered as a new therapeutic option for diabetic foot ulcers (DFUs). The regeneration potential of MSCs has been demonstrated in the experimental and clinical trials. Here we review the potential efficacy and systematic use of MSCs for the treatment of non-healing DFUs, current advances, MSC delivery systems, and possible options to enhance the therapeutic potential of stem cell for wound healing. © 2014 Mary Ann Liebert, Inc.

Mannose binding lectin, a plasma protein protects host from virus, bacteria, and parasites. Deficiency in MBL levels has been associated with susceptibility to various infectious diseases including P. falciparum malaria. Common MBL polymorphisms in promoter and coding regions are associated with decrease in plasma MBL levels or production of deformed MBL, respectively. In the present study, we hypothesized that MBL2 variants and plasma MBL levels could be associated with different clinical phenotypes of severe P. falciparum malaria.A hospital based study was conducted in eastern Odisha, India which is endemic to P. falciparum malaria. Common MBL-2 polymorphisms (codon 54, H-550L, and Y-221X) were typed in 336 cases of severe malaria (SM) [94 cerebral malaria (CM), 120 multi-organ dysfunction (MOD), 122 non-cerebral severe malaria (NCSM)] and 131 un-complicated malaria patients (UM). Plasma MBL levels were quantified by ELISA.Severe malaria patients displayed lower plasma levels of MBL compared to uncomplicated falciparum malaria. Furthermore, on categorization of severe malaria patients into various subtypes, plasma MBL levels were very low in MOD patients compared to other categories. Higher frequency of AB genotype and allele B was observed in MOD compared to UM (AB genotype: P = 0.006; B allele: P = 0.008). In addition, prevalence of YX genotype of MBL Y-221X polymorphism was also statistically more frequent in MOD case than UM (P = 0.009).The observations of the present study reveal that MBL-2 polymorphisms (codon 54 and Y-221X) and lower plasma MBL levels are associated with increased susceptibility to multi organ dysfunctions in P. falciparum malaria.
