It lacks the necessary throughput and resolution to provide a global overview of the dynamic molecular processes that take place in the different and rapidly growing populations and subpopulations of cells during organogenesis. (mpg.de)

A number of large biotech companies and scientists are looking toward stem cells as the basis for a therapeutic solution to cure such illnesses as blindness, diabetes and spinal cord injuries. (thefutureofthings.com)
In the second half of the twentieth century, scientists learned how to clone organisms in some species of mammals. (asu.edu)
In the 1950s, scientists generated entire frogs from embryonic frog cells. (cshl.edu)
The scientists at the Roslin Institute solved this problem by growing sheep udder cells under starvation conditions. (cshl.edu)
Scientists found that Dolly had the same DNA as the udder cells she came from. (cshl.edu)
The scientists have taken cells from Cumulina to make more clones. (cshl.edu)
Traditionally, scientists have worked with both embryonic and adult stem cells as research tools. (bioinformant.com)
Scientists initially created this line through embryonic stem cell retroviral gene trapping. (renmab.com)
Scientists identified embryonic stem cells that contained this as a proviral copy and injected them into blastocysts. (renmab.com)
No cells had the vector Gen-ROSAβgeo natively, which required scientists to create the ones needed from scratch. (renmab.com)
As such, scientists can use Rosa26 cells as marked wild alleles. (renmab.com)
Using the Rosa26 site, scientists created stable cell lines that included protein kinase A, CA-PKA. (renmab.com)
In total, the scientists were able to identify 38 different main cell types and over 500 subtypes. (mpg.de)

These haploid cells unite during fertilization to form a diploid zygote. (microbiologynote.com)
During this process, the zygote undergoes a sequence of cell divisions, resulting in the formation of distinct cell layers and the establishment of the body plan. (microbiologynote.com)
After the fusion of the egg cell with the sperm, the zygote transforms into a cluster of cells by serial cell divisions. (mpg.de)

There is also accelerating demand for extracellular vesicles (EVs) derived from stem cells, because they can act as intercellular messengers and may be able to exert therapeutic effects. (bioinformant.com)
Muscle regeneration declines with aging and myopathies, and reprogramming of differentiated muscle cells to their progenitors can serve as a robust source of therapeutic cells. (ca.gov)
These findings enhance understanding of cell-fate determination and create novel therapeutic approaches for improved muscle repair. (ca.gov)
This cell then has therapeutic cloning: the global the capacity to divide and grow into an exact replica of the original from whom the debate somatic cell was taken. (who.int)

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. (wikipedia.org)

Cardiomyocytes are terminally differentiated muscle mass cells in the adult mammalian heart, which do not divide. (bioinbrief.com)
Such cell transplantation therapies would need the effective seeding of as many as 1 108 donor cardiomyocytes per individual [4]. (bioinbrief.com)
16 , 17 In particular, transgenic zebrafish lines that express nfsB in β cells, cardiomyocytes, or other cell types have been established, and their exposure to the metronidazole leads to the targeted loss of these cells. (cdc.gov)

while p38 kinase inhibited cell develop into ectodermal cells and eventually differentiate into neural cells. (cusabio.com)

Sidebar Culture-derived Pluripotent Stem Cell lines Embryonal carcinoma cells (ECCs): derived from mouse teratocarcinomas these are the first PSC lines generated. (hiv-proteases.com)
But further research of the complex regulation of pluripotent stem cell identity revealed unexpected difficulties. (davidvilchezlab.com)
