Immortalization of a Cell Line with Neural Stem Cell (NSC) Characteristics Derived from Mouse Embryo Brain.

Neural stem cells (NSC) have been extensively used as a tool to investigate the mechanisms responsible for neural repair, and they have been also considered as the source for a series of promising replacement therapies in various neurodegenerative diseases. However, their use is limited by their relative rarity and anatomical localization, and also because the methods for isolation and characterization are usually time consuming and have some technical limitations.

Generation of a NESTIN-EGFP reporter human induced pluripotent stem cell line, KSCBi005-A-1, using CRISPR/Cas9 nuclease.

NESTIN, an intermediate filament, is a neuroectodermal marker involved in induced pluripotent stem cell (iPSC) differentiation toward neural lineages. Here, we introduced an EGFP reporter into the C-terminus of NESTIN in KSCBi005-A hiPSCs through homologous recombination using CRISPR/Cas9 nuclease. The successfully edited line was confirmed by sequencing and had a normal karyotype. It expressed EGFP upon induction of neural differentiation and exhibited potential for differentiation into three germ layers. ...

Stem Cell Aging? Blame It on the Niche.

The molecular basis for the neural stem cell quiescence-to-activation transition has become an important focus in the study of adult neurogenesis. Recently in Cell, Kalamakis et al. (2019) show that aged neural stem cells face greater barriers to exiting quiescence, imposed by the niche through inflammation and altered Wnt signaling.

Brain expansion promoted by polycomb-mediated anterior enhancement of a neural stem cell proliferation program.

During central nervous system (CNS) development, genetic programs establish neural stem cells and drive both stem and daughter cell proliferation. However, the prominent anterior expansion of the CNS implies anterior-posterior (A-P) modulation of these programs. In Drosophila, a set of neural stem cell factors acts along the entire A-P axis to establish neural stem cells. Brain expansion results from enhanced stem and daughter cell proliferation, promoted by a Polycomb Group (PcG)->Homeobox (Hox) homeotic n...

Improved neural differentiation of normal and abnormal iPSC lines in the presence of valproic acid.

During the generation of induced pluripotent stem cell (iPSC) lines from cord blood CD34 cells, a line having complete trisomy of chromosome 1 and deletion of q23 to qTer of chromosome 11 was accidentally developed in our lab. The abnormality was consistently detected even at higher passages. These chromosomal anomalies are known to manifest neurological developmental defects. In order to examine if such defects occur during in vitro differentiation of the cell line, we set up a protocol for neural differen...

Functional Multipotency of Stem Cells: Biological Traits Gleaned from Neural Progeny Studies.

In this review, a stem cell concept, initially defined by the author more than 10 years ago focusing on neural stem cells, has been systematically refined and updated. Relative to the conventional view which touched principally on the totipotency, pluripotentcy and multipotency of cell lineage differentiation (e.g., the ability of neural stem cells to grow into all three types of neural cells), accumulated data obtained by other researchers and my own team promoted Functional Multipotency; Totipotency; Plur...

The role of extracellular matrix on liver stem cell fate: A dynamic relationship in health and disease.

The liver stem cell niche is a specialized and dynamic microenvironment with biomechanical and biochemical characteristics that regulate stem cell behavior. This is feasible due to the coordination of a complex network of secreted factors, small molecules, neural, blood inputs and extracellular matrix (ECM) components involved in the regulation of stem cell fate (self-renewal, survival, and differentiation into more mature phenotypes like hepatocytes and cholangiocytes). In this review, we describe and summ...

Here, we established a CFTR knock-in reporter cell line from a human iPSC line (MHHi006-A) using TALEN technology. The reporter enables the monitoring and optimization of the differentiation of pluripotent stem cells into CFTR expressing epithelia on a single cell level, as well as the ...

Hematopoietic Stem Cell Intracellular Levels of Ca to the Rescue! What Next?

Calcium ions (Ca), ubiquitous signaling and second messenger molecules, are communicators for the transmission of messages in numerous cell functions. In this issue of Cell Stem Cell, Luchsinger et al. (2019) provide evidence through the use of transplantation and mechanistic studies for the finding that, "Harnessing Hematopoietic Stem Cell Low Intracellular Calcium Improves Their Maintenance In Vitro."

Generation of an integration-free human induced pluripotent stem cell line MUSIi010-A from occipital scalp fibroblasts of a male patient with androgenetic alopecia.

An induced pluripotent stem cell (iPSC) line, MUSIi010-A, was established by Sendai virus (SeV) transduction of scalp fibroblasts from a 59-year-old male with androgenetic alopecia (AGA). Pluripotency of the iPSC line was verified by immunofluorescence staining of pluripotent markers and by in vitro trilineage differentiation. The MUSIi010-A line was shown to retain normal karyotype and free of SeV vectors at passage 17. This iPSC line can be used for studying pathological mechanisms of AGA.

Recent advances ofinduced pluripotent stem cells application in neurodegenerative diseases.

Stem cell is defined by its ability to self-renewal and generates differentiated functional cell types, which are derived from the embryo and various sources of postnatal animal. These cellscan be divided according to their potential development into totipotent, unipotent, multipotent andpluripotent. Pluripotent is considered as the most important type due to its advantageous capability to create different cell types of the body in a similar behavior as embryonic stem cell. Induced pluripotent stem cells (i...
