2. From researches people have found a way of
regenerating fingers, I read this article about the
topic:
http://science.howstuffworks.com/environmental/life/human
-biology/extracellular-matrix.htm
This article is about a man who lost a
fingertip with a airplane model, and his
brother gave him a powder that helped to
regrow fingers. After some months the
finger was exactly the same as it was
before he flew it off.
After I read this I got very interested in the
topic and I wanted to research more about
it.
3. is the restoration of lost tissues and structures
from a cell known as a blastema.
Epimorphic Regeneration
4. Blastema is a mass of cells capable
of growing and regenerating into
organs or body parts.
Blastema
5. Historically
blastema have been
thought to be made of
undifferentiated pluripotent cells, but
recent research show that in some
organisms blastema may retain
memory of tissue origin.
Blastema
6. Blastemata is typically found in the early
stages of an organism's development such
as in embryos, and in the regeneration of
tissues, organs and bones.
Blastema
7. The epidermal cells from the edges
of the wound migrate and spread
over the exposed surface. This is
known as wound healing.
Description
8. A few days later, undifferentiated
cells accumulate inside the
epidermis, becoming a bulge. This is
known as regeneration bud or
blastema.
Blastema formation
9. Theblastema develops the missing
parts of the lost organ, like the digits
which grow into new digits.
Description
12. After several researches scientists have
found a way humans can regenerate
fingers.
Human fetuses can regenerate almost all
body parts wile they are in the womb. As
soon as they are born they lost that
ability.
Epimorphic regenerations in
Humans
13. According to regeneration researcher Dr.
Stephen Badylak of the University of
Pittsburgh, children up to the age of two
have been known to regrow fingertips
with no outside help.
14. The extract, called extracellular matrix,
lays the framework that cells use to
generate any given body part.
15. It holds the signals that tell cells to divide,
differentiate and build themselves into a
specific form. This extract can be use by
humans to regrow fingertips.
16. Let's take the case of a person who loses
the tip of a finger. When the finger is cut
off, the cells die, and their contents seep
into the surrounding tissue.
Examples
17. This alerts the immune system to a
problem. The immune system's response
to cell death is inflammation and scar
tissue. The formation of scar tissue
prevents any future cellular development
in the area.
18. When scars appear the cells can’t work,
and can’t repair the damage in top of that
skin.
