The development of 3D bio-printers has raised the prospects of making tissues and organs in a more affordable way and consistent way. Bangalore based start-up Next Big Innovation Lab has made human skin with its own 3D bio-printer using 3D bio-printing with a secret bio-ink.
History of bio-printing
Creation of human skin in a lab for commercial use dates back to 1993 when MatTek, a company founded by two chemical engineering professors at MIT, launched Epiderm.
They took live tissue cells from cosmetic surgeries and circumcisions, and then cultured them in petri dishes to produce skin. EpiDerm is a proven in vitro model system for chemical, pharmaceutical and skin care product testing.
Next Big Innovation Lab (NBIL) case: The NBIL has made human skin with its own 3D bio-printer using 3D bio-printing with a secret bio-ink. It has filed for patents related to its 3D bio-printing process and its bio-ink formulation is a trade secret. Using its internally developed 3D bio-printer gives NBIL a cost advantage.
The process of bio-printing
Stem cell engineering to grow all the cells of an organ in a personalised way to avoid rejection by the recipient’s immune system is another challenge. Researchers still hve to ensure that a lab organ will work with all the other organs in a human body.
