Summary: Attempts to generate functional blood cells from human pluripotent stem cells (hPSCs) remain largely unsuccessful, mainly due to the lack of understanding of the regulatory network of human hematopoiesis.

Location, Location, Location: Signals in Muscle Specification
Muscles control body movement and locomotion, posture and body position and soft tissue support. Mesoderm derived cells gives rise to 700 unique muscles in humans as a result of well-orchestrated signaling and transcriptional networks in specific time ...

Cell motility driving mediolateral intercalation in explants of Xenopus laevis [PDF]
In Xenopus, convergence and extension are produced by active intercalation of the deep mesodermal cells between one another along the mediolateral axis (mediolateral cell intercalation), to form a narrower, longer array.

Neural crest induction in Xenopus: evidence for a two-signal model [PDF]
We have investigated the molecular interactions underlying neural crest formation in Xenopus. Using chordin overexpression to antagonize endogenous BMP signaling in whole embryos and explants, we demonstrate that such inhibition alone is insufficient to ...

Epithelial-mesenchymal transitions: the importance of changing cell state in development and disease [PDF]
The events that convert adherent epithelial cells into individual migratory cells that can invade the extracellular matrix are known collectively as epithelial-mesenchymal transition (EMT).

Inhibition of Wnt activity induces heart formation from posterior mesoderm.
In the chick, heart mesoderm is induced by signals from the anterior endoderm. Although BMP-2 is expressed in the anterior endoderm, BMP activity is necessary but not sufficient for heart formation.

Stem/progenitor cells in the developing human lung
Human lungs are composed of more than 40 cell types. The lung is classified as a “conditionally renewing” tissue and is able of a quick response to cellular damage thanks to the presence of multiple stem/progenitor cells.

ABSTRACT The trunk axial skeleton develops from paraxial mesoderm cells. Our recent study demonstrated that conditional knockout of the stem cell factor Sall4 in mice by TCre caused tail truncation and a disorganized axial skeleton posterior to the lumbar level. Based on this phenotype, we hypothesized that, in addition to the previously

Adult-onset degeneration of adipose tissue in mice deficient for the Sox8 transcription factor
Although the transcription factor Sox8 is broadly expressed during embryogenesis in developing ectodermal and mesodermal tissues, mice develop surprisingly normally in the absence of Sox8.

Alternative Ways to Obtain Human Mesenchymal Stem Cells from Embryonic Stem Cells
Differentiation approaches to obtain mesenchymal stem cells (MSCs) have gradually developed over the last few decades. The problem is that different protocols give different MSC types, making further research difficult.
