Runx2+ Niche Cells Maintain Incisor Mesenchymal Tissue Homeostasis through IGF Signaling

Cell Reports, 2020
Summary: Stem cell niches provide a microenvironment to support the self-renewal and multi-lineage differentiation of stem cells. Cell-cell interactions within the niche are essential for maintaining tissue homeostasis.

Subtypes in pancreatic ductal adenocarcinoma based on niche factor dependency show distinct drug treatment responses

Journal of Experimental & Clinical Cancer Research, 2022
Background Pancreatic ductal adenocarcinoma (PDAC) is characterized by abundant stroma in which microenvironmental (niche) factors promote PDAC progression.

Hematopoietic Stem Cell Niche During Homeostasis, Malignancy, and Bone Marrow Transplantation

Frontiers in Cell and Developmental Biology, 2021
Self-renewal and multidirectional differentiation of hematopoietic stem cells (HSCs) are strictly regulated by numerous cellular components and cytokines in the bone marrow (BM) microenvironment.

Niche differentiation of bacteria and fungi in carbon and nitrogen cycling of different habitats in a temperate coniferous forest: A metaproteomic approach

, 2021
Temperate coniferous forests sustain the highest levels of biomass of all terrestrial ecosystems and belong to the major carbon sinks on Earth. However, the community composition and its functional diversity depending on the habitat have yet to be ...

Differential niche dynamics among major marine invertebrate clades [PDF]

Ecology Letters, 2013
AbstractThe degree to which organisms retain their environmental preferences is of utmost importance in predicting their fate in a world of rapid climate change. Notably, marine invertebrates frequently show strong affinities for either carbonate or terrigenous clastic environments.

Shifts in climate foster exceptional opportunities for species radiation: the case of South african geraniums. [PDF]

PLoS ONE, 2013
Climate change is often assumed to be a major driver of biodiversity loss. However, it can also set the stage for novel diversification in lineages with the evolutionary ability to colonize new environments.

Niche differentiation among clones in asexual grass thrips [PDF]

Journal of Evolutionary Biology, 2018
AbstractMany asexual animal populations comprise a mixture of genetically different lineages, but to what degree this genetic diversity leads to ecological differences remains often unknown. Here, we test whether genetically different clonal lineages of Aptinothrips grass thrips differ in performance on a range of plants used as hosts in natural ...

Loss of putzig in the germline impedes germ cell development by inducing cell death and new niche like microenvironments

Scientific Reports, 2019
Germline stem cell development and differentiation is tightly controlled by the surrounding somatic cells of the stem cell niche. In Drosophila females, cells of the niche emit various signals including Dpp and Wg to balance stem cell renewal and ...

Niche differentiation in a postglacial colonizer, the bank vole Clethrionomys glareolus

Ecology and Evolution, 2021
Species‐level environmental niche modeling has been crucial in efforts to understand how species respond to climate variation and change. However, species often exhibit local adaptation and intraspecific niche differences that may be important to ...
