Bioimpressão e produção de mini-órgãos com células tronco

Abstract

The bioprinting is considered a promising source in cell development, and production of mini-organs, valves, cartilage that may eventually be used in therapy for transplantation in animals and humans. It can also be used as an elective therapy in the treatment of injuries and treatment of chronic degenerative diseases. In humans, this therapy is been studied mainly in the treatment and regeneration of tissues printed from scaffold cells developed from stem cells, biomaterials and impressions in 3D. This technology is also an aid for the study of the formation of tumors, in order to design and evaluate the cellular proliferation of the tumors and the action of new chemotherapy drugs. However, the main drawback to this therapy is the lack of standardized protocols with reproducible and detailed methodologies with the aim of enabling the use of bioprinting and printing cells, tissues and organs in 3D. Thus, this review seeks to bring together the most current publications of the bioprinting area in order to describe the technique and its potential use as a therapeutic alternative.
