Applications of BiotechnologyTissue Replacement

Biotechnology and its common uses...

• It is the industrial use of biological processes from microorganism to make substances or to provide services

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.

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

• 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

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

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.

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)
