Gastrulation - Wikipedia, the free encyclopedia

Gastrulation is a phase early in the development of most animal embryos, during which the morphology of the embryo is dramatically restructured by cell migration. Gastrulation varies in different phy...

Germ layers—After the blastocyst stage of embryonic development, the inner cell mass of the blastocyst goes through gastrulation, a period when the inner cell mass becomes organized into three distinct cell layers, called germ layers.

To date, several laboratories have demonstrated that human ES cells in vitro are pluripotent; they can produce cell types derived from all three embryonic germ layers [1, 20, 38, 40].

Gastrulation produces three embryonic germ layers. ... Ectoderm [outer layer] develops into epidermis of skin and the nervous system. ... Mesoderm [middle layer] develops into skeletal, muscular, excretory, and the reproductive systems...

Human pluripotent stem cells can be derived from the inner cell mass of blastocysts (embryonic stem cells) or from the primordial germ cells of the gonadal ridge (embryonic germ cells;

Experiments with PTEN-null PGCs in culture revealed that these cells had greater proliferative capacity and enhanced pluripotent embryonic germ (EG) cell colony formation. PTEN appears to be essential for germ cell differentiation and an important factor in testicular germ cell tumor formation.

Primordial germ cells of the mouse cultured on feeder layers with leukemia inhibitory factor, ... These primordial germ cell-derived embryonic germ cells can be induced to differentiate extensively in culture, form teratocarcinomas when injected into nude mice and contribute to chimeras when injected into host blastocysts.

CEO Dr. James Kelly recently disclosed that SCI has produced multiple lines of human pluripotent stem cells. These cell lines are able to maintain their undifferentiated state and normal chromosome complement. The cells are produced without feeder layers (xenofree).

Guidelines for Human Embryonic Stem Cell Research Teratoma— A tumor composed of tissues from the three embryonic germ layers. Usually found in ovary or testis. Produced experimentally in animals by injecting pluripotent stem cells to determine the stem cells’ abilities to differentiate into various types of tissues.
