Ectoderm is one of the three primary germ layers in the very early embryo. The other two layers are the mesoderm (middle layer) and endoderm (most proximal layer), with the ectoderm as the most exterior (or distal) layer. It emerges and originates from the outer layer of germ cells. The word ectoderm comes from the Greek ektos meaning "outside", and derma, meaning "skin."
Multipotent amniotic fetal stem cells
A source of multipotent amniotic fluid / fetal stem cells (MAFSCs) is disclosed. MAFSC are of fetal origin and have a normal diploid karyotype. These cells are characterized by the following cell surface markers: SSEA3, SSEA4, Tra-1-60, Tra-1-81, Tra-2-54, HLA class I, CD13, CD44, CD49b, CD105 and are distinguished by the absence of the antigen markers CD34, CD45, and HLA Class II, but are distinguished from mouse embryonic stem cells in that these cells do not express the cell surface marker SSEA1. MAFSC express the stem cell transcription factor Oct-4. MAFSC cells can be propagated for an indefinite period of time in continuous culture in an undifferentiated state. The MAFSCs have the ability to differentiate in culture in a regulated manner, into three or more subphenotypes. Cells can then be differentiated into endodermal, mesodermal and ectodermal derived tissues in vitro and in vivo. A method for isolating, identifying, expanding and differentiating MAFSCs is disclosed.

Induction of pluripotent stem cells into mesodermal lineages
InactiveUS20080038820A1Promotes commitment and survivalGenetic material ingredientsSkeletal/connective tissue cellsProgenitorGerm layer
The present invention provides a method of inducing mesoderm derived cells from pluripotent stem cells. In contrast to methods known in the art that are often designed to replicate in vivo events of mesoderm induction, the present invention provides a unique, yet simple, method whereby pluripotent stem cells are mesodermally primed in the presence of factors that concomitantly inhibit the spontaneous differentiation of endoderm and ectoderm during expansion and suspension steps. Exposure and / or adherence of primed aggregates to a extracellular matrix that promotes the commitment and survival of induced mesoderm progenitors, followed by exposure to various mesoderm associated factors, allows for the subsequent induction of such cells into terminally differentiated lineages, such as cardiomyocytes. End products of this induction system will ultimately provide an unlimited source of mesoderm-derived cell types for therapeutic and pharmacological purposes.

The present invention makes available a method for inducing neuronal differentiation and preventing the death or degeneration of neuronal cells both in vitro and in vivo. The subject method stems from the unexpected finding that, contrary to traditional understanding of neural induction, the default fate of ectodermal tissue is neuronal rather than mesodermal and / or epidermal. In particular, it has been discovered that preventing or antagonizing a signaling pathway in a cell for a growth factor of the TGF-β family can result in neuronal differentiation of that cell.

System for inducing nerve stem cell differentiation and inducing method thereof
The invention discloses a method for preparing neural stem cells, which comprises a step of inductively culturing P19 cells in N2B27 culture medium to obtain a cell group containing neural stem cells above 94%. The method can culture the P19 cells in an environment without blood serum and retinoic acid, thus suppressing the interference of the blood serum with complex components and preventing the obtained neural stem cells from being transformed posteriorly by retinoic acid. Moreover, the method can directly transform pluripotent stem cells to neutral stem cells without resulting in selective cell apoptosis. The neutral stem cells obtained by the invention have anterior neutral plate characteristics and totipotency, and can well simulate the neurogenesis process in body. Accordingly, the neural stem cells can be used as the research model for analyzing neural induction and neural differentiation process from epiblast to neuroderm, thus providing an ideal path for researching development of embryo after nidation.
