Transplantation of adipocyte-derived stem cells in a hydrogel scaffold for the repair of cortical contusion injury in rats.

Adipocyte-derived stem cells have emerged as a novel source of stem cell therapy for their autologous and readily accessible and pluripotent potential to differentiate into different lineages such as neural stem cells (NSCs) and endothelial progenitor cells (EPCs). Transplantation of NSCs and EPCs has been promising for the repair of brain injury. We explored using co-transplanted hydrogel scaffold to improve the survival of the transplanted cells and recovery of neurological function.

[Differentiation of prostate cancer from benign prostatic disease by total prostate specific antigen dynamic profiles after transrectal prostate biopsy].

Objective: To investigate the possibility of differentiating prostate cancer (PCa) from benign prostatic disease by total prostate specific antigen (T-PSA) dynamic profiles following transrectal prostate biopsy, and to determine the cutoff value of the T-PSA ratio between pre- and post-biopsy.

Methods: A total of 36 men at the mean age of 69.89 years with increased serum PSA underwent prostate biopsy guided by transrectal ultrasound, followed by measurement of T-PSA at 10, 30, 60 and 90 min, plotting of T-PSA dynamic profiles and calculation of the pre- and post-biopsy T-PSA ratio at different time points.

[Effect of superparamagnetic iron oxide labeling on neural stem cell survival and proliferation].

Objective: To study the effect of superparamgnetic iron oxides (ferumoxides) on the survival and proliferation of neural stem cells (NSCs) and determine the optimal ferumoxides concentration for labeling.

Methods: Bone marrow stromal cells (BMSCs) were obtained from rat femoral marrow and cultured in vitro to induce their differentiation into NSCs. Ferumoxides labeling of the NSCs was performed with different final concentrations of ferumoxides, and the labeling efficiency and viability of the labeled NSCs were evaluated by Prussian blue staining, MTT assay, flow cytometry and transmission electron microscope.

In vitro culture and induced differentiation of adult rat neural stem cells from the corpus striatum.

Objective: To investigate the in vitro multipotential differentiation of neural stem cells from adult rat corpus striatum.

Methods: The neural stem cells isolated from adult rat corpus striatum were cultured in serum-free medium to obtain cell suspension before monoclonal subculturing and differential induction. Immunocytochemical staining and reverse transcriptional PCR (RT-PCR) were performed to identify the properties of the differentiated cells.
