Abstract

Poor survival of stem cells in the harsh microenvironment at the site of stroke, especially during acute phase of injury, remains a serious obstacle to achieve the desired prognosis. We hypothesized that combined treatment of neural stem cells (NSCs) with small molecules would precondition them to become robust and survive better as compared with the native nonpreconditioned cells. Mouse ganglionic NSCs were isolated, cultured, and characterized. The cells were preconditioned by treatment with sodium butyrate (NaB) and nicorandil (Nico) and transplanted in an experimentally induced stroke model. Sham-operated animals without treatment or animals with experimental stroke treated with basal medium, native NSCs, NSCs preconditioned with NaB or Nico alone were used as controls. The tissue samples and cells with different treatments were used to measure brain-tissue-derived neurotrophic factor (BDNF) level and the activity of phosphatidylinositol-3 kinase (PI3K), apurinic/apyrimidinic endonuclease 1 (APE1), and nuclear factor-κB (NF-κB) p50 both in vitro and in vivo, respectively. Additionally, survival of the cells and recovery indices for stroke were studied. The combined treatment with NaB + Nico resulted in increased BDNF level ...Continue Reading

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.
