A newly created cell model of the amniotic sac could reveal new insights into early pregnancy, as well as generate helpful ...

Fetal Membranes The fetal membranes consist of the chorion, amnion, yolk sac, and allantois. The chorion has three layers: cytotrophoblastic, chorionic connective tissue, and basement membrane.

Brain macrophages serve diversified niches in the brain to maintain the organ’s homeostasis, and can play pathogenic roles in age-related brain disease. Hoping to one day replace dysfunctional ...

AFP (produced by the fetal yolk sac) and β-HCG (secreted by placental trophoblastic tissue) are glycoproteins that may be elevated in patients with germinomas.

The yolk sac plays an important part in the early stages of pregnancy. Find out what it does and how it works.

Identification of distinct yolk sac-derived macrophage subpopulations in the fetal liver reveals their crucial role in shaping the hematopoietic niche, impacting erythropoiesis and granulopoiesis ...

The analysis focused on the hematopoietic cells from which immune cells are derived, as well as on the yolk sac (YS) and the aorta-gonad-mesonephros (AGM), which are involved in hematopoiesis during ...

a: Experimental schematic. Cells are isolated from the fetal yolk sac and AGM and their transcripts are sequenced by next-generation sequencing. b: Cell groups from single-cell analysis of AGM ...
