Distant activation of Notch signaling induces stem cell niche assembly.

open access: yesPLoS Genetics, 2021
Here we show that multiple modes of Notch signaling activation specify the complexity of spatial cellular interactions necessary for stem cell niche assembly.

E-Ras improves the efficiency of reprogramming by facilitating cell cycle progression through JNK–Sp1 pathway

open access: yesStem Cell Research, 2015
We have previously shown that pluripotent stem cells can be induced from adult somatic cells which were exposed to protein extracts isolated from mouse embryonic stem cells (mESC).

M-CSF from Cancer Cells Induces Fatty Acid Synthase and PPARβ/δ Activation in Tumor Myeloid Cells, Leading to Tumor Progression

open access: yesCell Reports, 2015
We investigate crosstalk between cancer cells and stromal myeloid cells. We find that Lewis lung carcinoma cells significantly induce PPARβ/δ activity in myeloid cells in vitro and in vivo.

Restoring bone marrow niche function rejuvenates aged hematopoietic stem cells by reactivating the DNA Damage Response

open access: yesNature Communications, 2023
Aging associated defects within stem cell-supportive niches contribute towards age-related decline in stem cell activity. However, mechanisms underlying age-related niche defects, and whether restoring niche function can improve stem cell fitness, remain

Functional complexity of hair follicle stem cell niche and therapeutic targeting of niche dysfunction for hair regeneration

open access: yesJournal of Biomedical Sciences, 2020
Stem cell activity is subject to non-cell-autonomous regulation from the local microenvironment, or niche. In adaption to varying physiological conditions and the ever-changing external environment, the stem cell niche has evolved with multifunctionality

Nanoparticle-encapsulated siRNAs for gene silencing in the haematopoietic stem-cell niche

open access: yesNature Biomedical Engineering, 2020
Bone-marrow endothelial cells in the haematopoietic stem-cell niche form a network of blood vessels that regulates blood-cell traffic as well as the maintenance and function of haematopoietic stem and progenitor cells.

Cardiac stem cell niches

open access: yesStem Cell Research, 2014
The critical role that stem cell niches have in cardiac homeostasis and myocardial repair following injury is the focus of this review. Cardiac niches represent specialized microdomains where the quiescent and activated state of resident stem cells is regulated.

Headcase promotes cell survival and niche maintenance in the Drosophila testis. [PDF]

open access: yesPLoS ONE, 2013
At the apical tip of the Drosophila testis, germline and somatic stem cells surround a cluster of somatic cells called the hub. Hub cells produce a self-renewal factor, Unpaired (Upd), that activates the JAK-STAT pathway in adjacent stem cells to ...

Plant stem cell niches

open access: yesThe International Journal of Developmental Biology, 2005
Stem cells are required to support the indeterminate growth style of plants. Meristems are a plants stem cell niches that foster stem cell survival and the production of descendants destined for differentiation. In shoot meristems, stem cell fate is decided at the populational level.

Regenerative medicine for male infertility: A focus on stem cell niche injury models

open access: yesBiomedical Journal, 2022
Stem and progenitor cells located within stem cell niches maintain the renewal and regeneration of tissues and organs throughout the life of an adult organism.
