Stem Cell Chip
Stem cell chip is a device that detects given biochemical changes in stem cells, for example changes in RNA Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and deoxyribonucleic acid ( DNA) are nucleic acids. Along with lipids, proteins, and carbohydra ... expression. References See also * Stem cell genomics Stem cells {{Genetics-stub ...

Stem Cells
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50–150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. ''In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. However, when ...

Stem Cell Genomics
Stem cell genomics analyzes the genomes of stem cells. Currently, this field is rapidly expanding due to the dramatic decrease in the cost of genome sequencing, sequencing genomes. The study of stem cell genomics has wide reaching implications in the study of stem cell biology and possible therapeutic usages of stem cells. Application of research in this field could lead to drug discovery and information on diseases by the molecular characterization of the pluripotent stem cell through DNA and transcriptome sequencing and looking at the epigenetic changes of stem cells and subsequent products. One step in that process is single cell phenotypic analysis, and the connection between the phenotype and genotype of specific stem cells. While current genomic screens are done with entire populations of cells, focusing in on a single stem cell will help determine specific signaling activity associated with varying degrees of stem cell differentiation and limit background due to heterogeneous p ...
