Developmental biology of hematopoiesis [PDF]

open access: yesBlood, 1995
The cellular and environmental regulation of hematopoiesis has been generally conserved throughout vertebrate evolution, although subtle species differences exist. The factors that regulate hematopoietic stem cell homeostasis may closely resemble the inducers of embryonic patterning, rather than the factors that stimulate hematopoietic cell ...

Counteractive and cooperative actions of muscle β-catenin and CaV1.1 during early neuromuscular synapse formation

open access: yesiScience, 2022
Summary: Activity-dependent calcium signals in developing muscle play a crucial role in neuromuscular junction (NMJ) formation. However, its downstream effectors and interactions with other regulators of pre- and postsynaptic differentiation are poorly ...

Developmental biology of lichens [PDF]

open access: yesNew Phytologist, 1993
SUMMARYLichen‐forming fungi are a large, taxonomically diverse group of nutritional specialists which acquire fixed carbon from a population of minute green algal or cyanobacterial cells. Mycobionts of foliose or fruticose lichens differ from the rest of the fungi by expressing morphologically and anatomically complex symbiotic phenotypes.

Seed mineral reserves and vigour of Bambara groundnut (Vigna subterranea L.) landraces differing in seed coat colour

open access: yesHeliyon, 2019
A newly emerged seedling, given light and water, but no external source of minerals, uses its internal mineral nutrient reserves effectively for an early establishment.

Apicosome: Newly identified cell-type-specific organelle in mouse cochlear and vestibular hair cells

open access: yesiScience, 2023
Summary: Cochlear and vestibular hair cells are highly specialized sensory receptors for hearing and balance. Here, we report a serendipitous identification of a hair-cell-specific organelle in neonatal mouse inner ear, which we name “apicosome.” The ...

A small molecule-based strategy for endothelial differentiation and three-dimensional morphogenesis from human embryonic stem cells

open access: yesHeliyon, 2016
The emerging models of human embryonic stem cell (hESC) self-organizing organoids provide a valuable in vitro platform for studying self-organizing processes that presumably mimic in vivo human developmental events. Here we report that through a chemical

Sox9 regulates melanocytic fate decision of adult hair follicle stem cells

open access: yesiScience, 2023
Summary: The bulge of hair follicles harbors Nestin+ (neural crest like) stem cells, which exhibit the potential to generate various cell types including melanocytes.

Increasing Diversity in Developmental Biology

open access: yesFrontiers in Sociology, 2022
The demographic profile of the scientific and biomedical workforce in the United States does not reflect the population at large (https://ncses.nsf.gov/pubs/nsf21321/data-tables; www.census.gov), raising concerns that there will be too few trained ...

Single cell expression analysis of primate-specific retroviruses-derived HPAT lincRNAs in viable human blastocysts identifies embryonic cells co-expressing genetic markers of multiple lineages

open access: yesHeliyon, 2018
Chromosome instability and aneuploidies occur very frequently in human embryos, impairing proper embryogenesis and leading to cell cycle arrest, loss of cell viability, and developmental failures in 50–80% of cleavage-stage embryos.
