AbstractThe trend of regenerative therapy for diabetes in human and veterinary practices has conceptually been proven according to the Edmonton protocol and animal models. Establishing an alternative insulin-producing cell (IPC) resource for further clinical application is a challenging task. This study investigated IPC generation from two practical canine mesenchymal stem cells (cMSCs), canine bone marrow-derived MSCs (cBM-MSCs) and canine adipose-derived MSCs (cAD-MSCs). The results illustrated that cBM-MSCs and cAD-MSCs contain distinct pancreatic differentiation potential and require the tailor-made induction protocols. The effective generation of cBM-MSC-derived IPCs needs the integration of genetic and microenvironment manipulation using a hanging-drop culture of PDX1-transfected cBM-MSCs under a three-step pancreatic induction protocol. However, this protocol is resource- and time-consuming. Another study on cAD-MSC-derived IPC generation found that IPC colonies could be obtained by a low attachment culture under the three-step induction protocol. Further, Notch signaling inhibition during pancreatic endoderm/progenitor induction yielded IPC colonies through the trend of glucose-responsive C-peptide secretion. Thus, this study showed that IPCs could be obtained from cBM-MSCs and cAD-MSCs through different induction techniques. Also, further signaling manipulation studies should be conducted to maximize the protocol’s efficiency.

On the basis of the force analysis of two mobile mechanisms containing a mobile closed contour the theoretical preconditions of creation of self-adjusted mechanisms is developed. The load design of mechanism is executed on the basis of the proved theorem of a derivative on a time from the force moment. Brand new property of self-adjustment is found. Mechanism self-adjustment allows it to be independently conforming to variable external loading by change of speed. Property of self-adjustment allows creating the mechanisms with variable transfer ratio depending on loading. Self-adjusted mechanisms are simple on the device and are working without a control system. Self-adjusted mechanisms (for example, self-adjusted gear boxes) are determining a new highly effective generation of drives of machines with variable technological resistance.
