Final answer:
Current tissue engineering research aims to adapt cells from injured organs to grow replacement tissues and use stem cells to cover damaged tissues, both of which aim to renew and repair body tissues without the risk of rejection.
Step-by-step explanation:
Goals of Current Research in Tissue Engineering
One primary goal for current research in tissue engineering is to adapt cells from an injured organ to produce replacement tissue. This process involves harvesting cells from an individual, which are then used to grow new organs or tissues in vitro. This method is beneficial as it allows transplantation without the risk of rejection, as the new tissues would contain the individual's own cells. Another goal is using stem cells as a covering for damaged tissue. Stem cells have the ability to divide and differentiate into specialized cell types, which enable them to repair and renew body tissues. Their undifferentiated state allows them to be used in various forms of therapy, with the potential to greatly improve the quality of life and save lives of those with debilitating conditions.
Moreover, advancements are being made in creating scaffolds that can serve as an extracellular microenvironment to further encourage tissue regeneration. These scaffolds are designed to provide not only structural support but also to integrate with the human body effectively, promoting wound healing and tissue regeneration.
