Background information

1. Where did stem cells originate, and how did they come to surface has a medical advancement?

Stem cells are originated from two major sources i.e. the adult tissue and the embryos. The research and use of stem cell has remained a controversial issue because of the utilization of embryonic stem cells that derive from unborn babies. The reason to use these stem cells is their ability to develop into any kind of cell needed. These stem cells are acquired from four to five days mature embryos that are in the blastocyst stage of growth. The cells are obtained from the inner cell mass (Nishanth, 2011).

On the other hand, Adult stem cells are originated from a range of places conditional on why they are required. Adult stem cells also known as somatic cells can be discovered in various kinds of tissue like liver, bone marrow, blood, skin, skeletal muscles and the brain. These cells are believed to have not as much ability to distinguish into any cell type and are more probable to redevelop into the type of tissue from which they originated.

Now, stem cells are developed in laboratories to form dedicated cells for the revival of nerves and muscle in the course of cell culture. Extremely adjustable stem cells that originate from the bone marrow and umbilical cord are commonly used in various medical therapies. The research on stem cell contributed to achieve a primary perceptive of how organisms raise and develop and how the tissues are upheld during the adult life. Human keratinocytes are required for tissue manufacturing of skin functional in tissue regeneration and repair targetted at clinical purpose. Specified the current interest in the prospective use of adult and embryonic stem cells for fundamental and advanced research, together with assessing the cause of human cancer, efforts have been made to exemplify markers that would make out these stem cells. The assurance of the therapy based on stem cell for research progression in regenerative medicine has encouraged a good number of clinical examinations, predominantly for previously incurable diseases. Transplantation of stem cell by means of cell substitution or as vector for the delivery of gene is an impending strategy for the cure of neurodegenerative diseases like Parkinson's disease, Alzheimer's disease, Huntington's chorea, multiple sclerosis, HIV-associated dementia, glaucoma, amyotrophic lateral sclerosis caused by unlike mechanisms. The pluripotent stem cells derived from the bone marrow hold a great assurance for therapeutic fixation of wounded central nervous system (Duran & George, 2011).

Embryonic Stem Cells

1. Why it's considered to be medically sound

a. Diseases it's capable of curing

b. Its ability to form into any cell

c. It's ability to regenerate into multiple stem cells

As the name suggests, embryonic stem cells are originated from embryos. And majority of embryonic stem cells are actually originated from embryos that grow from eggs that are fertilized in a vitro fertilization clinic and after that provided for the purpose of research with informed approval from the ...
