Final answer:
The ICM found in humans and mice compared to stem cells found in sponges and hydra differ in terms of the presence of pluripotent cells, method of reproduction, cellular differentiation potential, and use in medical therapies.
Step-by-step explanation:
Difference between ICM found in humans and mice compared to stem cells found in sponges and hydra:
A) Presence of pluripotent cells:
Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) found in humans and mice have the presence of pluripotent cells, which means they have the ability to differentiate into cells of all three germ layers (endoderm, mesoderm, and ectoderm).
Stem cells found in sponges and hydra are multipotent, meaning they have a limited differentiation potential and can only differentiate into specific cell types found in those organisms.
B) Method of reproduction:
Humans and mice reproduce sexually, and their stem cells are derived from embryos or adult tissues.
Sponges and hydra reproduce asexually, and their stem cells are derived from their body tissues.
C) Cellular differentiation potential:
ICM found in humans and mice can differentiate into various cell types, including specialized cells of different tissues and organs.
Stem cells found in sponges and hydra have a more limited differentiation potential and can only differentiate into specific cell types needed for the growth and regeneration of those organisms.
D) Use in medical therapies:
ICM derived stem cells, such as hESCs and iPSCs, have the potential to be used in medical therapies due to their ability to differentiate into various cell types for tissue repair and regeneration.
Stem cells found in sponges and hydra are not currently used in medical therapies as they are specific to those organisms and may not have the same therapeutic potential as pluripotent stem cells found in humans and mice.
