摘要:
Provided herein are methods for determining ethanol exposure of a prenatal subject, including measuring whether or not amniotic fluid stem cells collected from amniotic fluid surrounding the prenatal subject have a upregulation or expression of one or more genes of a first predetermined combination and/or a downregulation of expression of one or more genes of a second predetermined combination. Also provided are methods for determining ethanol exposure of a prenatal subject which methods include measuring alkaline phosphatase activity and/or calcium deposition of amniotic fluid stem cells collected from amniotic fluid surrounding the prenatal subject.
摘要:
The invention is directed to methods for preparing artificial blood vessels by preconditioning a matrix seeded with endothelial cells to fluid flow conditions that mimic blood flow.
摘要:
The present invention concerns methods of screening cells for differentiation or de-differentiation, and/or for status as a pluripotent or multipotent (e.g., “stem”) cell, by detecting the differential expression (e.g., upregulation, downregulation) of genes.

Provided herein is an endothelial scaffold comprising, consisting of, or consisting essentially of decellularized corneal stroma. In some embodiments, the scaffold has cultured endothelial cells seeded thereon. Methods of treating a patient in need of corneal endothelial transplant are also provided, including implanting the scaffold as described herein onto a cornea of the patient (e.g., by deep keratectomy).
摘要:
The present invention relates to compositions and methods for mimicking an in vivo environment for culturing cells in vitro. The in vivo mimicking environment is based on the generation of a tissue-specific extracellular matrix wherein the matrix provides a substrate for which the cultured cell originated from. The tissue-specific extracellular matrix can further comprise a component of a whole tissue-specific homogenate.

摘要:
The present invention provides methods and compositions of engineered cells for use in the continuous or transient delivery of growth factors and angiogenesis modulating agents, such as vascular endothelial growth factor (VEGF), in conjunction with constructs for replacing or augmenting organ functions. In one aspect of the invention, the genetically engineered cells can be immature cells that are capable of differentiating and assimilating into the target region. The methods of the present invention can be used to enhance vascularization locally at a target site in need of repair, growth, or implantation through the incorporation of autologous cells which have been genetically engineered to secrete a growth factor or angiogenesis modulating agent.

摘要:
A method of treating diabetes in a mammalian subject is carried out by: (a) providing mammalian amniotic fluid stem cells, and then (b) administering the cells to the subject in an amount effective to treat diabetes. Optionally, the cells may be differentiated into pancreatic-like cells or at least treated to initiate subsequent differentiation into-pancreatic-like cells, prior to administration.
