Cells, Stem Cells, and Cancer Stem Cells [PDF]

Seminars in Reproductive Medicine, 2013
The stem cell field owes a great deal to the previous work conducted by embryologists and researchers devoted to reproductive medicine. The time is coming when this emerging field will pay off in the reproductive sciences by offering new avenues of understanding gametogenesis and early embryonic development.

PI3K-C2 alpha Knockdown Results in Rerouting of Insulin Signaling and Pancreatic Beta Cell Proliferation [PDF]

, 2018
Insulin resistance is a syndrome that affects multiple insulin target tissues, each having different biological functions regulated by insulin. A remaining question is to mechanistically explain how an insulin target cell/tissue can be insulin resistant ...

Cell-by-Cell Deconstruction of Stem Cell Niches [PDF]

Cell Stem Cell, 2020
Single-cell sequencing approaches offer exploration of tissue architecture at unprecedented resolution. These tools are especially powerful when deconvoluting highly specialized microenvironments, such as stem cell (SC) niches. Here, we review single-cell studies that map the cellular and transcriptional makeup of stem and progenitor niches and discuss

Establishment and content of sugars and phenols in Physalis callus obtained from different explants and concentrations of bap and naa - doi: 10.4025/actascibiolsci.v36i1.18074

Acta Scientiarum: Biological Sciences, 2013
Obtaining cells of Physalis pubescens is of interest for studies of primary and secondary metabolic pathways, in the search for new active molecules. Our objectives were to evaluate the regeneration potential of explants from different parts of the plant,

The cell secretome, a mediator of cell-to-cell communication [PDF]

Prostaglandins & Other Lipid Mediators, 2015
We are witnessing the emergence of a novel type of biological regulation, namely, the communication between cells via their secreted substances, the secretome. This brief overview is based on the available published data and our own experience. We discuss three vignettes illustrating the importance of communication via the secretome: (1) the secretome ...

Modulation of Peptidoglycan Synthesis by Recycled Cell Wall Tetrapeptides

, 2020
The bacterial cell wall is made of peptidoglycan (PG), a polymer that is essential for the maintenance of cell shape and survival. During growth, bacteria remodel their PG, releasing fragments that are predominantly reinternalized and recycled.

Two homologous Agr-like quorum-sensing systems cooperatively control adherence, cell morphology, and cell viability properties in Lactobacillus plantarum WCFS1 [PDF]

, 2008
A two-component regulatory system of Lactobacillus plantarum, encoded by genes designated lamK and lamR (hpk10 and rrp10), was studied. The lamK and lamR genes encode proteins which are highly homologous to the quorum-sensing histidine kinase LamC and ...

Effect of Pore Size on Cell Behavior Using Melt Electrowritten Scaffolds

Frontiers in Bioengineering and Biotechnology, 2021
Tissue engineering technology has made major advances with respect to the repair of injured tissues, for which scaffolds and cells are key factors. However, there are still some issues with respect to the relationship between scaffold and cell growth ...
