A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
Stem cells have the amazing potential to evolve into many distinct cell kinds in the body throughout early life and growth. Additionally, in many tissues they assist as a sort of interior repair system by dividing up essentially without limit to replace other cells as long as the person or animal is still alive. When a stem cell splits up, each new cell has the potential either to stay a stem cell or become another kind of cell with a more specialized function, such as a red blood, muscle cell, or a brain cell. The Pluripotent stem cells offers the possibility of a renewable source of replacement cells and tissues to heal a myriad of infections, situation, and disabilities including Parkinson's disease, spinal cord injury, amyotrophic lateral sclerosis, diabetes, burns, heart disease, and arthritis. An alternative theory is that stem units stay undifferentiated due to environmental cues in their particular niche. Stem cells differentiate when they depart that niche or no longer obtain those signals. Until lately, researchers have primarily worked with two kinds of arise units from animals and humans: embryonic stem units and non-embryonic "somatic" or "adult" stem units. Human stem cells could furthermore be utilized to test new drugs.
