Human population entered the 20th century with 1.6 billion people and left the century with 6.1 billion. The growth of the last 200 years appears explosive on the historical timeline. The overall effects of this growth on living standards, resource use, and the environment will continue to ...
CD4+cells (17.1% of T cells) and sparse numbers of regulatory T (Treg) cells (Fig.2a,b). We identified a PD-1+-activated population of Tregcells with a TIM-3+LCK+subset that accounted for >50% of this population (Fig.2a,b). Notably, both Tregcells and NKT cells...
Current in vitro differentiation paradigms focuses on replicating extrinsic signaling of fetal development to guide progenitors through a “natural” developmental timeline. Such a model primarily views differentiation as a spatial occurrence that is dependent on environmental niche cues (i.e., extrinsic ...
Pretty much as for language, one can think of diverse functions for which music might have been selected—and even estimate a timeline for the selection of each type of function. Most of the functions of music mentioned in the previous section can be characterized as “external” to the subje...
a Schematic of the brief timeline of the generation of small human cerebral organoids from human pluripotent stem cells. b Quantification of cortical cell populations in vitro at day 30 postdifferentiation (n = 30 organoids). c, g Representative immunostaining of human cerebral organoids for...
The anterior pituitary gland plays a central role in regulating various physiological processes, including body growth, reproduction, metabolism and stress response. Here, we perform single-cell RNA-sequencing (scRNA-seq) of 4113 individual cells from hu
Archaeogenomic studies have largely elucidated human population history in West Eurasia during the Stone Age. However, despite being a broad geographical region of significant cultural and linguistic diversity, little is known about the population histor
A Schematic illustration of the CRS and FMT procedures, with the respective groups labeled above the timeline. In brief, mice were randomly assigned to the CTR and CRS group after 1 week of acclimatization. The CRS modeling lasted for 2 weeks and was followed by the first behavioral tests (...
