In the human embryo
Pluripotent stem cells, i.e. cells that can give rise to any fetal or adult cell type, can be found in a number of tissues, including umbilical cord blood. Using genetic reprogramming, pluripotent stem cells equivalent to embryonic stem cells have been derived from human adult skin tissue.  Adult stem cells. Adult or somatic stem cells exist throughout the body after embryonic development and are found inside of different types of tissue. These stem cells have been found in tissues such as the brain, bone marrow, blood, blood vessels, skeletal muscles, skin, and the liver. Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Commonly, stem cells come from two main sources: 1  Embryos formed during the blastocyst phase of embryological development (embryonic stem cells) and. 2  Adult tissue (adult stem cells). Adult stem cells have been identified in many organs and tissues, including brain, bone marrow, peripheral blood, blood vessels, skeletal muscle, skin, teeth, heart, gut, liver, ovarian epithelium, and testis. They are thought to reside in a specific area of each tissue (called a stem cell niche). IV. An adult stem cell is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ. The adult stem cell can renew itself and can differentiate to yield some or all of the major specialized cell types of the A stem cell is essentially the building block of the human body. Stem cells are capable of dividing for long periods of time, are unspecialized, but can develop into specialized cells. The earliest stem cells in the human body are those found in the human embryo. The stem cells inside an embryo will eventually give rise to every cell, tissue and organ in the fetus's body. Unlike a regular cell, which can only replicate to create more of its own kind of cell, a stem cell is pluripotent. 1 Embryonic stem cells-Embryonic stem cells include those found within the embryo, the fetus or the umbilical cord blood. 2  Depending upon when they are harvested, embryonic stem cells can give rise to just about any cell in the human body. 3  Adult stem cells-Adult stem cells can be found in infants, children and adults Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.  Okay. This is a biggie. In the human body there are two types of stem cells. 1.) Adult stem cells These cells are found all around the body. However, they can only turn into certain types of cells. For example, in bone marrow, there are stem cells called hematopoietic stem cells-they can only turn into certain types of blood cells. I.E. white blood cells, red blood cells, platelets, and other blood factors Report Abuse. The stem cells in a human adult are usually found all over the body. they primarily attend to the function of cell replenishment and repair. these adult or somatic stem cells can be sourced from a simple tissue of a human body for research. Source(s): wikipedia. Best Answer: stem cells that is causing all the controversy comes from embryonic tissue they haven't taken on a final role so can have the potential to become a different type of cell such as a cell for a heart or liver but stem cells are found in human organs. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells.
