3D bioprinting is an innovative process that creates cell patterns within a defined space using advanced 3D printing technologies. This method preserves the function and viability of the cells in the printed structure, making it a revolutionary approach in medical applications.
In India, 3D bioprinting is primarily used to produce human tissues for drug testing and potential transplantation. This technology enables researchers to create tissue models that closely mimic natural human tissues, enhancing the accuracy of drug testing.
The amendment made in 2023 allowed researchers to utilize alternative methods, such as 3D bioprinted tissues, to assess the safety and efficacy of new drugs. This shift significantly reduces the reliance on animal testing, promoting ethical research practices while accelerating the development of new therapies.
Several key players are advancing the field of 3D bioprinting in India. Notable institutions include Pandorum Technologies, the Indian Institute of Technology (IIT) Hyderabad, and the Indian Institute of Science (IISc) Bangalore. These organizations are focused on developing bioengineered tissues and advanced biomaterials for various medical applications.
The 3D bioprinting process involves printing living cells layer by layer to replicate the architecture of natural tissues. A specialized bioink, composed of polymers, living cells, and growth-supportive components, is utilized to ensure optimal cell growth and functionality.
The location of the LIGO-India facility in Hingoli, Maharashtra, plays a crucial role in its operation. The geographical positioning of this gravitational-wave observatory is essential for enhancing the detection sensitivity of the LIGO network, enabling more accurate observations.
Future applications of 3D bioprinting in India are promising. These include advancements in pharmaceutical drug testing and the development of tissues or organs for medical repair or replacement. Indian laboratories are actively working on creating various tissue models, particularly for skin, liver, and cornea.
Utilizing Indian silk as a biopolymer in bioprinting presents significant cost advantages. Indian silk is considerably cheaper than purified collagen and possesses unique biological properties that promote cell proliferation, making it a viable and cost-effective option for tissue engineering.
Anticipation surrounds the commercialization of bioprinted tissues and organs in India. Certain models, particularly skin and cornea, are expected to be ready for drug and toxicity screening within a year. Clinical trials for various applications are projected to commence in the subsequent years.
