We have employed a peptide-based antibody generation protocol for producing antibody against human nestin. Using a 12-mer synthetic peptide from repetitive region of human nestin protein devoid of any N- or O-glyco-sylation sequences, we generated a mouse monoclonal antibody capable of recognizing human, mouse, bovine, and rat nestin. A wide variety of nestin proteins ranging from 140-250 kDa was detected by this antibody. This antibody is highly specific and functional in applications such as ELISA, flow cytometry, immunocytochemistry, and Western blot assays.

This study defines biochemical mechanisms that contribute to novel neural-regenerative activities we recently demonstrated for thiol-modified ManNAc analogs in human neural stem cells (hNSCs) by comparing our lead drug candidate for brain repair, "TProp," to a "size-matched" N-alkyl control analog, "But." These analogs biosynthetically install non-natural sialic acids into cell surface glycans, altering cell surface receptor activity and adhesive properties of cells. In this study, TProp modulated sialic acid-related biology in hNSCs to promote neuronal differentiation through modulation of cell adhesion molecules (integrins α6, β1, E-cadherin, and PSGL-1) and stem cell markers.

Objectives: This study investigated the impact of hypoxic preconditioning on the survival and oxidative stress tolerance of nestin-expressing hair follicle stem cells (hHFSCs) and SH-SY5Y neuroblastoma cells, two crucial cell types for central nervous system therapies. The study also examined the relative expression of three key genes, HIF1α, BDNF, and VEGF following hypoxic preconditioning.
Materials And Methods: hHFSCs were isolated from human hair follicles, characterized, and subjected to hypoxia for up to 72 hours.

Objective: Pancreatic cancer is characterized by low survival rate and rapid deterioration. Methyltransferase-like 14 (METTL14), as N6-methyladenosine (m6A) methyltransferase, is closely related to tumor progression. The purpose of this study is to look into how METTL14 affects pancreatic cancer tumorigenesis, cell division, and apoptosis.

Background: Embryoid bodies (EBs) are three-dimensional (3D) multicellular cell aggregates that are derived from stem cell and play a pivotal role in regenerative medicine. They recapitulate many crucial aspects of the early stages of embryonic development and is the first step in the generation of various types of stem cells, including neuronal stem cells. Current methodologies for differentiating stem cells into neural embryoid bodies (NEBs) in vitro have advanced significantly, but they still have limitations which necessitate improvement.
