Stability and Hopf bifurcation in a mathematical model of pluripotent stem cell dynamics [PDF]

Nonlinear Analysis Real World Applications 6, 4 (2005) 651-670, 2009
We study a mathematical model describing the dynamics of a pluripotent stem cell population involved in the blood production process in the bone marrow. This model is a differential equation with a time delay. The delay describes the cell cycle duration and is uniformly distributed on an interval. We obtain stability conditions independent of the delay.

Naïve-like pluripotency to pave the way for saving the northern white rhinoceros from extinction

Scientific Reports, 2022
The northern white rhinoceros (NWR) is probably the earth’s most endangered mammal. To rescue the functionally extinct species, we aim to employ induced pluripotent stem cells (iPSCs) to generate gametes and subsequently embryos in vitro.

Porcine OCT4 reporter system as a tool for monitoring pluripotency states

Journal of Animal Reproduction and Biotechnology, 2021
Pluripotent stem cells could self-renew and differentiate into various cells. In particular, porcine pluripotent stem cells are useful for preclinical therapy, transgenic animals, and agricultural usage. These stem cells have naïve and primed pluripotent

Fish Pluripotent Stem-Like Cell Line Induced by Small-Molecule Compounds From Caudal Fin and its Developmental Potentiality

Frontiers in Cell and Developmental Biology, 2022
The technique of induced pluripotent stem cells has significant application value in breeding and preserving the genetic integrity of fish species. However, it is still unclear whether the chemically induced pluripotent stem cells can be induced from non-

Non-human primate pluripotent stem cells for the preclinical testing of regenerative therapies

Neural Regeneration Research, 2022
Non-human primates play a key role in the preclinical validation of pluripotent stem cell-based cell replacement therapies. Pluripotent stem cells used as advanced therapy medical products boost the possibility to regenerate tissues and organs affected ...

Absence of Rybp Compromises Neural Differentiation of Embryonic Stem Cells

Stem Cells International, 2016
Rybp (Ring1 and Yy1 Binding Protein) is a transcriptional regulator and member of the noncanonical polycomb repressive complex 1 with essential role in early embryonic development.

Induced pluripotent stem cells and cerebral organoids from the critically endangered Sumatran rhinoceros

iScience, 2022
Summary: Less than 80 Sumatran rhinos (SR, Dicerorhinus sumatrensis) are left on earth. Habitat loss and limited breeding possibilities are the greatest threats to the species and lead to a continuous population decline.

Using single-cell entropy to describe the dynamics of reprogramming and differentiation of induced pluripotent stem cells [PDF]

, 2020
Induced pluripotent stem cells (iPSCs) provide a great model to study the process of reprogramming and differentiation of stem cells. Single-cell RNA sequencing (scRNA-seq) enables us to investigate the reprogramming process at single-cell level. Here, we introduce single-cell entropy (scEntropy) as a macroscopic variable to quantify the cellular ...

A mathematical modelling framework for the regulation of intra-cellular OCT4 in human pluripotent stem cells [PDF]

arXiv, 2021
Human pluripotent stem cells (hPSCs) have promising clinical applications in regenerative medicine, drug-discovery and personalised medicine due to their potential to differentiate into all cell types, a property know as pluripotency. A deeper understanding of how pluripotency is regulated is required to assist in controlling pluripotency and ...
