🔑 Different methods to restore organ function, including stem cell implantation, transplantation, tissue engineering, and organoids.
⚙️ Transplantation is a common strategy where healthy tissue or organ is replaced with a damaged one, with autologous, allogeneic, or xenogeneic sources.
⭐️ The success of transplantation depends on anatomical compatibility and the possibility of rejection.
🧬 Immunological compatibility is crucial in organ transplantation, including matching blood type and genetic markers.
🔬 Different types of immune responses can occur, including acute and chronic rejection, mediated by antibodies and memory cells.
💉 Lymphocytes play a key role in the immune response during organ transplantation.
🔬 Autologous transplants minimize tissue damage and immune rejection, allowing for better tissue function restoration.
🦾 Prosthetic devices, such as dental implants and joint replacements, serve as permanent anatomical components.
🧬 Stem cell implementation shows promise in regenerating and differentiating into various tissues.
🔑 Stem cells can give rise to different germ layers, including mesoderm, ectoderm, and endoderm.
🧪 There are two types of adult stem cells: hematopoietic and mesenchymal stem cells.
⚕️ When implanted, stem cells can differentiate into tissue cells and secrete factors for tissue repair and regeneration.
🧪 Tissue engineering aims to develop functional tissues by combining cells, a support matrix, and biomolecules.
💡 Advancements have been made in treating diseases like heart attacks and valve defects through tissue restoration.
🔬 The button-up strategy in tissue engineering involves organizing cells and components using methods like 3D printing.
🔍 Induced pluripotent stem cells (iPS cells) have the potential to develop into organs through controlled differentiation.
🧪 Organoids, small laboratory-grown organs, lack a vascular system, limiting their growth and nutrient supply.
🔬 Organoids serve as experimental models in vitro for studying diseases and developing treatments.
🔧 To create complex organ architectures, methods like 3D printing technology are utilized.
🌞 Ultraviolet light and photons can be used to treat loss of organ function.
🧪 Methods like estereolitografía and sacrificial substrates can create complex structures and support vascularization.
🌱 Organoids have the ability to undergo neurovascularization and require accompanying vascular cells.
