AMIEL-PEREZ, José; AMIEL-SAENZ, José  and  AMIEL-TORRELIO, María. Organoids: fundamentals, present and future. Rev. perú. med. exp. salud publica [online]. 2022, vol.39, n.2, pp.227-235.  Epub June 30, 2022. ISSN 1726-4634.  http://dx.doi.org/10.17843/rpmesp.2022.392.10203.

Organoids are tiny structures, mainly generated from induced pluripotent stem cells, which are cultured in the laboratory while retaining their innate or acquired characteristics. They have the potential to reproduce biological development processes, model pathological processes that will enable the discovery of new drugs and promote regenerative medicine. However, these processes require constant improvement because variations may have occurred in the constitution of the organs. Therefore, this article aims to review updated information on organoids and their basic and recent experimental processes, starting with gastrulation, in an attempt to mimic, as much as possible, the formation of the three layers: ectoderm, mesoderm and endoderm; as well as the information regarding the factors involved in the induction, differentiation and maturation during the generation of organoids. Likewise, the design and preparation of highly specialized culture media that allow obtaining the selected organ with the highest precision and safety. We searched for original and review articles published in PubMed, Nature and Science. Articles were selected for their abstracts and full text. The conclusions of this article highlight the future advantages in the use and applications of organoids.

Keywords : Induced pluripotent stem cells; Gastrulation; Design matrix; Three-dimensional cultures; Cell differentiation; Signal transduction; Cell maturation; Microchip; Embryonal stem cells; Growth factors.
