Quantitative microscopy of the Drosophila ovary shows multiple niche signals specify progenitor cell fate. [PDF]

open access: yes, 2017
Adult stem cells commonly give rise to transit-amplifying progenitors, whose progeny differentiate into distinct cell types. It is unclear if stem cell niche signals coordinate fate decisions within the progenitor pool.

Pluripotent stem cells and their dynamic niche [PDF]

open access: yes, 2016
Cell-seeded implants are a regenerative medicine strategy that aims to replace injured tissue and restore tissue function. Pluripotent stem cells are promising cell candidates for the development of regenerative medicine therapies as they have the ...

Neutral competition of stem cells is skewed by proliferative changes downstream of Hh and Hpo. [PDF]

open access: yes, 2014
Neutral competition, an emerging feature of stem cell homeostasis, posits that individual stem cells can be lost and replaced by their neighbors stochastically, resulting in chance dominance of a clone at the niche.

Role of the bone morphogenic protein pathway in developmental haemopoiesis and leukaemogenesis [PDF]

open access: yes, 2016
Myeloid leukaemias share the common characteristics of being stem cell-derived clonal diseases, characterised by excessive proliferation of one or more myeloid lineage.

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.

Designing stem cell niches for differentiation and self-renewal [PDF]

open access: yes, 2018
Mesenchymal stem cells, characterized by their ability to differentiate into skeletal tissues and self-renew, hold great promise for both regenerative medicine and novel therapeutic discovery. However, their regenerative capacity is retained only when in

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

The Stem Cell Niche in Regenerative Medicine [PDF]

open access: yes, 1987
Stem cells are fundamental units for achieving regenerative therapies, which leads naturally to a theoretical and experimental focus on these cells for therapeutic screening and intervention.

First steps to define murine amniotic fluid stem cell microenvironment [PDF]

open access: yes, 2016
Stem cell niche refers to the microenvironment where stem cells reside in living organisms. Several elements define the niche and regulate stem cell characteristics, such as stromal support cells, gap junctions, soluble factors, extracellular matrix ...

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 ...
