background: the present study was designed to evaluate the survival and proliferation of spermatogonial stem cells from cryptorchid mouse testis in co-culture system over a 3 weeks period. materials and methods: sertoli and spermatogonial cells were isolated from bilateral cryptorchid mouse model testes. isolated spermatogonial cells were co-cultured with sertoli cells in minimal essential medi...
Trials to replace the pancreatic ? cells that are destroyed by this autoimmune disease raising hopes of a cure.
The kynurenine pathway (KP) of tryptophan metabolism is linked to antimicrobial activity and modulation of immune responses but its role in stem cell biology is unknown. We show that human and mouse mesenchymal and neural stem cells (MSCs and NSCs) express the complete KP, including indoleamine 2,3 dioxygenase 1 (IDO) and IDO2, that it is highly regulated by type I (IFN-β) and II interferons (I...
PURPOSE The geometry of the proximal femur is one of the important factors for choosing the suitable stem. We have been applied cemented collarless polished tapered (CPT) stem to the patients with small femur. Radiographic evaluation was performed to access the clinical feature of the stem in early stage of the follow-up. METHODS One hundred total hip arthroplasties with CPT system were perfo...
Search for a cure for type-1 diabetes mellitus has lead to many avenues of research, all having the same objective: to replace the lost beta cells and prevent their further destruction by the immune system. Transplantation of islets of Langerhans seems closer to achieving this goal with the recent introduction of new improved immunosuppressive protocols including monoclonal antibodies against t...
Periprosthetic fractures of the femur present a challenging surgical problem. The aim of this study was to evaluate the outcome of periprosthetic femoral fractures (PFF) which were treated with internal fixation or stem revision. Depending on the fracture type in the Duncan-Vancouver-Classification, 42 patients with PFF were treated either with a Fixateur interne (n = 23) in cases with type B1 ...
Analysis of type II diabetes mellitus adipose-derived stem cells for tissue engineering applications
To address the functionality of diabetic adipose-derived stem cells in tissue engineering applications, adipose-derived stem cells isolated from patients with and without type II diabetes mellitus were cultured in bioreactor culture systems. The adipose-derived stem cells were differentiated into adipocytes and maintained as functional adipocytes. The bioreactor system utilizes a hollow fiber-b...
