Induced pluripotent stem cells were first generated by Shinya Yamanaka and Kazutoshi Takahashi at Kyoto University, Japan, in 2006. [1] They hypothesized that genes important to embryonic stem cell (ESC) function might be able to induce an embryonic state in adult cells.
The term stem cell was coined by Theodor Boveri and Valentin Haecker in late 19th century. [8] Pioneering works in theory of blood stem cell were conducted in the beginning of 20th century by Artur Pappenheim, Alexander A. Maximow, Franz Ernst Christian Neumann.
Progenitor cells have become a hub for research on a few different fronts. Current research on progenitor cells focuses on two different applications: regenerative medicine and cancer biology.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells.
The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability, reading instructions from punched celluloid film.
Many organisms, including aspen trees, reproduce by cloning, often creating large groups of organisms with the same DNA.One example depicted here is quaking aspen.. Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means.
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3]
Transcription occurs in the nucleus using DNA as a template to produce mRNA.In eukaryotes, this mRNA molecule is known as pre-mRNA as it undergoes post-transcriptional modifications in the nucleus to produce a mature mRNA molecule.
