2. Biotechnology and its common
uses...
• It is the industrial use of
biological processes from
microorganism to make
substances or to provide
services

3. Tissue Engineering
• Tissue engineering is the use of combinations
of cells, different material methods, and bio
and physiochemical processes to improve or
replace biological tissues
• It is the replacement of damaged or diseased
tissues
• Its purpose is to maintain or improve damaged
tissues or whole organ
• The first such product to gain approval for
clinical use was a form of artificial skin
consisting of a thin sheet of collagen gel
infiltrated with two layers of cultured human
cells.

4. Factors tissue engineering relies
upon…
• Tissue engineering relies on 4 important factors:
 Right cells to do the job
 Right environment such as scaffold to support the cells
 Right biomolecules like growth factors to make the
cells healthy and productive
 Physical and chemical process to influence the
development of the cells

5. • Cells are important for tissue
engineering because cells collide to
make up a tissue and then they carry
out the function
• Tissues that are mostly required are
 Skin
 Muscle
 Bone
• Regeneration of entire organ is too
possible
 Heart
 Kidney
 Liver

6. Process
• To harvest cells directly from the target organ
• Need a structure for support that is the scaffold it comes in different sizes
• Gives a structure to cells for their better growth
• Human stem cells are mostly used, they can be used to make any tissue of the body
• Putting cells in the write environment is crucial for the proper nourishment and growth

8. In vitro meat
• Cultured meat, also called , cell-
cultured meat, and in vitro meat, is
meat grown in cell culture instead of
inside animals. Cultured meat is
produced using many of the
same tissue engineering techniques
traditionally used in regenerative
medicine. Cultured meat has not yet
been commercialized due to some
technical challenges. The first cultured
beef burger patty was created by
Dr. Mark Post and was eaten at a
demonstration for the press in London.

9. Artificial Organs
• Artificial organs are classed
into four groups:
 Bone or joint replacement
(knee, finger or hip bones)
 Skin or soft tissue
replacement (skin, muscle)
 Internal organs (heart,
kidney, liver, pancreas)
 Sensory organs (eye, ear)
