Single-cell analysis is a valuable tool for dissecting cellular heterogeneity in complex systems 1. However, a comprehensive single-cell atlas has not been achieved for humans. Here we use single-cell mRNA sequencing to determine the cell-type composition of all major human organs and cons .

Mesenchymal stem cells are characterized morphologically by a small cell body with a few cell processes that are long and thin. The cell body contains a large, round nucleus with a prominent nucleolus, which is surrounded by finely dispersed chromatin particles, giving the nucleus a clear appearance. The remainder of the cell body contains a small amount of Golgi apparatus, rough . Here we describe the development of a long-term feeder-free, chemically defined culture system for distal lung progenitors as organoids derived from single adult human alveolar epithelial type II (AT2) or KRT5 + basal cells. AT2 organoids were able to differentiate into AT1 cells, and basal cell organoids developed lumens lined with.
Haematopoiesis (/ h ɪ ˌ m æ t oʊ p ɔɪ ˈ iː s ɪ s, ˈ h iː m ə t oʊ-, ˌ h ɛ m ə-/, from Greek αἷμα, 'blood' and ποιεῖν 'to make'; also hematopoiesis in American English; sometimes also h(a)emopoiesis) is the formation of blood cellular components. All cellular blood components are derived from haematopoietic stem cells. In a healthy adult person, approximately 10 Guo et al. provide a transcriptional cell atlas of the fetal and postnatal human testes. Remarkably, starting from ∼14 weeks postfertilization, fetal primordial germ cells transition to a cell state highly similar to postnatal spermatogonial stem cells. Furthermore, somatic niche specification precedes this transition, which is consistent with guiding fetal germline development.
These researchers are able to remove the genes necessary to reprogram an adult cell into a stem cell after the reprogramming step is complete. March 9, — President Barack Obama signs Executive Order to repeal some of the restrictions on human embryonic stem cell research funds placed by the previous administration.
