In order to improve the structure and function of acute spinal cord injury, the present study investigated the effect of electro-acupuncture (EA) on the differentiation of mesenchymal stem cells (MSCs) and the regeneration of nerve fibers in transected spinal cord of rats. The differentiation of MSCs into neuron-like cells and neuroglial cells and regeneraton of 5-hydroxytrptamine (HT) nerve fi...
BACKGROUND Ovarian tissue (OT) cryopreservation and transplantation are options for fertility preservation in young female cancer patients. METHODS We investigated xenotransplantation of human OT into back muscle (B) of severe combined immunodeficiency mice. OT follicle content was evaluated by stereomicroscopy and pre-transplantation. Xenograft survival, follicular development (with/without ...
Islet cell transplantation has been associated with ultimate graft rejection. This preliminary study investigates the use of the renal subcapsular region as a site for placement of canine islet cell allografts. A new noncollagenase mechanical technique was used for preparation of the allografts. Animals in group I (N = 6) died of hyperglycemia in 4.0 +/- 1.89 days (X +/- SD) after pancreatectom...
Modular tissue engineering for the vascularization of subcutaneously transplanted pancreatic islets.
The transplantation of pancreatic islets, following the Edmonton Protocol, is a promising treatment for type I diabetics. However, the need for multiple donors to achieve insulin independence reflects the large loss of islets that occurs when islets are infused into the portal vein. Finding a less hostile transplantation site that is both minimally invasive and able to support a large transplan...
BACKGROUND Ovarian tissue transplantation is emerging technologies for fertility preservation. In addition, in vitro maturation (IVM) of oocytes retrieved from ovarian tissues may overcome the fertility defects in certain cases. OBJECTIVE The aim was to evaluate the best site for ovarian tissue transplantation in mice. Also, feasibility of IVM of oocytes retrieved from auto grafted ovarian ti...
Improved therapeutic assessment of experimental traumatic brain injury (TBI), using mesenchymal stem cells (MSCs), would immensely benefit its therapeutic management. Neurometabolite patterns at injury site, measured with proton magnetic resonance spectroscopy (1H-MRS) after MSCs transplantation, may serve as a bio-indicator of the recovery mechanism. This study used in vivo magnetic resonance ...
A major goal of Schwann cell (SC) transplantation for spinal cord injury (SCI) is to fill the injury site to create a bridge for regenerating axons. However, transplantation of peripheral nerve SCs requires an invasive biopsy, which may result in nerve damage and donor site morbidity. SCs derived from multipotent stem cells found in skin dermis (SKP-SCs) are a promising alternative. Regardless ...
