摘要:
In some aspects, cultures of neurons derived from human induced pluripotent stem cells (iPS cells) that exhibit synchronous firing of neural networks are provided. In some embodiments, neuronal activity of the cultures may be detected or measured using a multi-electrode array.
摘要:
This application relates to a method for differentiating pluripotent stem cells (PSCs) into cardiomyocytes. Moreover this application relates to a method for differentiating human embryonic stem cells (h ESCs) and induced pluripotent stem cells (i PSCs) into defined cardiomyocytes based on linked steps of chemically defined medium inductions.
摘要:
The present invention relates to a method of immobilizing a cell on a support, the method comprising a) providing a compound or salt thereof comprising, preferably consisting of, one or more hydrophobic domains attached to a hydrophilic domain, wherein the one or more hydrophobic domains are covalently bound to said hydrophilic domain, and wherein the one or more hydrophobic domains each comprise a linear lipid, a steroid or a hydrophobic vitamin, and wherein the hydrophilic domain comprises a polyethylene glycol (PEG) moiety, and wherein the compound comprises a linking group; b) contacting a cell with the compound under conditions allowing the interaction of the compound with the membrane of the cell, thereby immobilizing the linking group on the surface of the cell; and c) contacting the linking group immobilized on the cell with a support capable of binding the linking group, thereby immobilizing the cell on the support.
摘要:
Model systems and methods for exploring mechanisms of carcinogenesis and the acquisition of metastatic ability, and to provide insights into potential therapeutic targets. The systems include and methods involve fusion of a stem cell and a genetically altered cell to evaluate carcinogenesis and metastasis (Fig. 4) and for the discovery and evaluation of new therapeutic targets to inhibit metastasis and other markers of carcinogenesis.

摘要:
Markers useful for the identification, characterization and, optionaily, the enrichment or isolation of tumorigenic cells or cell subpopulations are disclosed.
摘要:
The present disclosure relates to an Extra Cellular Matrix composition specific for cancer type and a tumor microenvironment platform for long term culturing of tumor tissue, wherein said culturing provides human ligands and tumor tissue micro-environment to mimic physiologically relevant signalling systems. The present disclosure further relates to the development of a Clinical Response Predictor and its application in the prognostic field (selection of treatment option for the patient) and translational biology field (development of anticancer drugs). The disclosure further relates to a method of predicting clinical response of a tumor patient to drug(s). The disclosure further relates to a method for screening tumor cells for the presence of specific markers for determining the viability of said cells for indication of tumor status.
摘要:
Methods for determining cell chirality using micropattemed substrates are disclosed. Also provided are methods for diagnosing diseases such as genetic diseases or cancer by comparing the chirality of sample cells from a subject with normal cells, and determining a difference in chirality between the sample cells and normal cells.
摘要:
The present invention provides three-dimensional microenvironment niches prepared from biomaterial compositions that supports growth and self renewal of stem cells. The invention also provides methods for inducing pluripotency in a somatic cell using chemical compounds, as well as methods for screening for compounds that can induce pluripotency in a somatic cell.
