One Cell Build Entire Organism!!
Every cell originates from a single cell which is the fertilized egg. For becoming a specialized cell such as blood, heart or nerve cells, it follows a genetic program. This genetic program identifies the identity of a cell, its features, and functions.
Around 40,000 cells of 25 different types were isolated from zebrafish over a period of nine hours. To investigate the maturation of cells, RNA was analyzed, a copy of genetic material.
The genetic program that a cell follows on the way to maturity and path to development is more flexible than expected. So far it was assumed that the developing of a cell is a predetermined path like marbles rolling down a hill which stops its rolling at some point of time. But the study now has proved that cells leave their initial trajectory, change their path and takes a new identity.
Pluripotent stem cells can be turned into any cell type in the body. They are used as a key therapeutic resource for incurable conditions such as heart failure, Parkinson disease, and blindness. They are used for studying various diseases and to test new drugs in human cells.
Scientists discovered that by treating ordinary skin cells with certain proteins, pluripotent stem cells can be formed which is helpful for various incurable conditions.
Another study shows turning of skin cells into stem cells using CRISPR. CRISPR is a powerful tool that can manipulate a genome by targeting a unique sequence of DNA. That sequence of DNA will be deleted permanently or will be replaced. It can also temporarily turn on or off a DNA.
Genetics plays important role in every cell, its function, regulation, mutation etc., Hence one cell can build entire organism by using its genetic program.
