synthesis assembly
have been used to prepare polymer Nanofibers
in recent years.

26. ECM is the main component of all types of
connective tissues (bone, cartilage, tendon and
blood vessels)
So, most Nanoscaffolds and related stem-
cell applications will be associated with
the engineering of connective tissues.

27. As Stem cells are able to proliferate and
differentiate into required tissue, but they
need a 3-dimensional structure for their
growth and support.
So, the Nanofibrous scaffolds are
combined with stem cells in tissue
engineering.

29. ECM Composition (cont’d)

31. Ranging
Composed of a from 500
copolymer to 800 nm
PLGA fibers in

Their morphological characteristics were
similar to those of the ECM in natural
tissue.

38. Conclusion

39. Conclusion
Nanotechnologies are beginning to be implemented as
analytical and production tools in stem cell–based
therapeutic approaches.
Only a few tools available in the field of nanoscience have
been made available to advance the use of stem cells in
medicine

40. L'avenir
The gap between scientists
traditionally involved in
nanoscience and scientists
dealing with biotechnology will
be bridged during the coming
years, leading to an increased
use of nanotools in biomedicine.

41. The future looks bright…
We envision the application of nanotechnology in studies of:

42. Totally radical future
No doubt, this will drive stem-cell therapy closer to
clinical application in human beings.
