Development of Human Embryonic and Fetal Dermal Vasculature

Journal of Investigative Dermatology, 1989
This report summarizes recent advances in the understanding of the structure and organization of the microvasculature in developing human skin. Previous observations suggested that the skin contains no blood vessels as late as eight weeks estimated gestational age (EGA).

Tissue distribution of the laminin β1 and β2 chain during embryonic and fetal human development [PDF]

Journal of Molecular Histology, 2010
Laminins are the major glycoproteins present in all basement membranes. Previously, we showed that perlecan is present during human development. Although an overview of mRNA-expression of the laminin β1 and β2 chains in various developing fetal organs is

Circadian clocks during embryonic and fetal development

Birth Defects Research Part C: Embryo Today: Reviews, 2007
AbstractCircadian rhythmicity is a fundamental characteristic of organisms, which helps ensure that vital functions occur in an appropriate and precise temporal sequence and in accordance with cyclic environmental changes. Living beings are endowed with a system of biological clocks that measure time on a 24‐hr basis, termed the circadian timing system.

Striated Musculature: Embryonic and Fetal Development

International Journal of Morphology
SUMMARY: The different embryological origins of striated muscle tissue make it an interesting tissue but at the same time difficult to understand, this is how the musculature of the face comes from the first pharyngeal arch, on the other hand. The muscles of the tongue derive from the somites.

NR2F2 is required in the embryonic testis for Fetal Leydig Cell development

AbstractMale genital development in XY mammalian fetuses is triggered by the action of hormones, including testosterone, secreted by the developing testes. Defects in this process are a cause for Differences in Sex Development (DSD), one of the most common congenital abnormalities in humans.

NR2F2 regulation of interstitial cell fate in the embryonic mouse testis and its impact on differences of sex development. [PDF]

Nat Commun
Testicular fetal Leydig cells produce androgens essential for male reproductive development. Impaired fetal Leydig cell differentiation leads to differences of sex development including hypospadias, cryptorchidism, and infertility.

Retracted: The human placenta is a hematopoietic organ during the embryonic and fetal periods of development

Developmental Biology, 2009
We studied the potential role of the human placenta as a hematopoietic organ during embryonic and fetal development. Placental samples contained two cell populations-CD34(++)CD45(low) and CD34(+)CD45(low)-that were found in chorionic villi and in the chorioamniotic membrane.
