Why stem cell called stem cells?

Answer 1

One reason that stem cells are important is due to human development from stem cells. As such, an understanding of their unique attributes and control can teach us more about early human development. Diseases such as cancer are thought to result from abnormal cell proliferation and differentiation. This means that an understanding of where things go 'wrong' in stem cell division and thus lead to cancer can help us find ways to prevent the dysfunctional changes or employ effective ways to treat them with targeted drugs.

Answer 2

Stem cells are premature cells only found in fetuses that have the ability to develop as any type of body cell. They are being researched because they can help in surgery and further develop medical treatment to people who can't produce certain cells.

Answer 3

It involves the research of embryonic stem cells, which are the earliest stage human embryos. The artificial fertilization of egg cells usually results in these stem cells, which can be implanted in a human female to impregnate her. Study of these embryos can also assist in genetic research, but it still remains controversial.

Answer 4

"The term stem cell appears in the scientific literature as
early as 1868 in the works of the eminent German biologist
ErnstHaeckel(Haeckel,1868).Haeckel, a major supporter

of Darwin's theory of evolution, drew a number of phyloge-

netic trees to represent the evolution of organisms by de-

scent from common ancestors and called these trees

''Stammba ¨ume''(German for family trees or ''stemtrees'').

In this context, Haeckel used the term ''Stammzelle'' (Ger-

man for stem cell) to describe the ancestor unicellular

organism from which he presumed all multicellular organ-

isms evolved (Haeckel, 1868, 1874). In the revised 3rd

edition of his book Anthropogenie (Haeckel, 1877),

Haeckel made one of his characteristic leaps from evolu-

tion (phylogeny) to embryology (ontogeny) and proposed

that the fertilized egg also be called stem cell. That is,

Haeckel used the term stem cell in two senses: as the

unicellular ancestor of all multicellular organisms and as

the fertilized egg that gives rise to all cells of the organism.

Uses of the term stem cell referring to a distinct cell in

the embryo capable of giving rise to more specialized cells

can be found later in that century"
