Abstract
Objective We proposed a novel differentiation method for the efficient differentiation of adipose-derived mesenchymal stem
cells (ADMSCs) into functional insulin-producing cells (IPCs) based on MafA overexpression.
Materials and Methods In this experimental study, a eukaryotic expression vector containing MafA [MafA/pcDNA3.1(+)]
was constructed and purified. ADMSCs were differentiated into IPCs. ADMSCs were assigned in two groups including
control (C), and the MafA overexpressed (MafA+) groups. The ADMSCs were transfected by MafA/pcDNA 3.1(+) at day
10 of the differentiation. Differentiated cells were analyzed for the expression of multiple β cell specific genes (Nkx2.2,
Ngn3, Isl-1, Pdx1, MafA, Nkx6.1, and Insulin) using real-time polymerase chain reaction (PCR). The insulin secretion
potency of the differentiated cells in response to glucose exposure was also determined using an enzyme-linked
immunosorbent assay (ELISA) method and Dithizone (DTZ) staining. The IPCs from the control manipulated group,
and un-differentiated ADMSCs group were transplanted to streptozotocin (STZ)-diabetic rats. Rats were monitored for
blood glucose and insulin concentration.
Results The results revealed that ADMSCs were successfully differentiated into IPCs through the 14 day differentiation
protocol. The expression of β-cell specific genes in MafA+ IPCs was higher than in control cells. Glucose-induced
insulin secretion after the exposure of IPCs to glucose was higher in MafA+ group than the control group. The STZ-
diabetic rats showed an ability to secrete insulin and apparent hyperglycemic condition adjustment after transplantation
of the control IPCs. The mean insulin concentration of diabetic rats that were transplanted by manipulated IPCs was
significantly higher than ADMSCs-transplanted rats; however, no effect was observed in the concentration of blood
glucose.
Conclusion The overexpression of MafA can be used as a novel promising approach for the efficient production of
IPCs from ADMSCs in vitro. However, the future therapeutic use of the MafA+ IPCs in diabetic animals needs further
investigations.

Abstract
Pancreatic and duodenal homeobox 1 (Pdx1) and Sonic hedgehog (Shh) are the key regulators of beta-cell function. In vitro experiments have shown that there is significant cooperation between Pdx1 and Shh with regard to the production and maintenance of insulin-producing cells (IPCs). In this study, the combined effect of Pdx1 overexpression and Shh manipulation on the function of adipose tissue-derived IPCs was determined. A eukaryotic expression vector (Pdx1- pCDNA3.1(+)) was constructed and transfected into a Chinese hamster ovary (CHO) cell line. Adipose tissue-derived mesenchymal stem cells (ADMSCs) obtained from rats were assigned to two groups [control (C) and manipulated (M)] and differentiated into IPCs. Manipulated cells were treated with a mixture of FGF-β and cyclopamine and recombinant Shh protein at days 3 and 11, respectively, and transfected with Pdx1- pCDNA3.1(+) at day 10. The expression of multiple genes related to function of beta cells was analyzed using real-time PCR. The functionality of IPCs in vitro was analyzed through dithizone (DTZ) staining and ELISA. IPCs were injected into the tail vein of diabetic rats, and blood glucose and insulin concentrations were measured. CHO cells transfected with Pdx1- pCDNA3.1(+) showed a significantly higher expression of Pdx1 compared with nontransfected cells. Manipulated IPCs exhibited a significantly higher expression of MafA, Nkx2.2, Nkx6.1, Ngn3, insulin, and Isl1 and a higher insulin secretion in response to glucose challenge in relation to control cells. Rats that received manipulated IPCs exhibited a higher ability to normalize blood glucose and insulin secretion when compared to controls. Our protocol might be used for more efficient cell therapy of patients with diabetes in the future.

Abstract
BACKGROUND AIMS Sonic hedgehog (Shh) is an intercellular signaling molecule that regulates pancreas development in mammals. Manipulation of Shh signaling pathway can be used as reliable approach to improve the generation of functional insulin-producing cells (IPCs) from mesenchymal stromal cells (MSCs). METHODS In the present study, a novel differentiation protocol was used to produce IPCs from adipose tissue-derived MSCs (ATDMSCs) based on sequential inhibition and reactivation of Shh pathway. ATDMSCs were differentiated into IPCs via a 14-day basic protocol using 1% insulin transferrin selenium (ITS) and 1% nicotinamide in Dulbecco's Modified Eagle's Medium medium. A mixture of 0.25 µmol/L cyclopamine + 64 ng/mL basic fibroblast growth factor at day 3 of differentiation and 150 ng/mL recombinant Shh at day 11 of differentiation were used, respectively, to promote sequential inhibition and reactivation of Shh pathway. Insulin granule formation, glucose-stimulated insulin secretion and gene expression pattern related to the pancreatic endocrine development and function were analyzed in manipulated and unmanipulated IPCs. RESULTS IPCs obtained after Shh manipulation secreted higher amounts of insulin in vitro. This phenotype was accompanied by increased expression of both genes critical for β-cell function and transcription factors associated with their mature phenotype including Pdx1, MafA, Nkx2.2, Nkx6.1, Ngn3, Isl1 and insulin at day 14 of differentiation. CONCLUSIONS Our findings indicated that the early inhibition and late reactivation of Shh signaling pathway during the differentiation of ATDMSCs improved the functional properties of IPCs, a novel method that could be considered as an alternative approach for cell-based therapy for type 1 diabetes.
