INDIA: British Prime Minister Boris Johnson begins his two-day visit to India.

The video discusses the availability of materials for 3D printing in the market, the process of loading materials suitable for cells, and printing structures layer by layer. It highlights the future potential of printing functional tissues, such as ears and cardiac tissues, in labs. The ultimate goal is to create regenerative machines for tissue engineering, allowing the study of tissues in lab settings before transferring them to human bodies. The video confirms that the cells used are from real living organisms, specifically heart cells.
