Erecta Family Genes Regulate The Shoot Apical Meristem And Organ Formation, Daniel A. Degennaro
Erecta Family Genes Regulate The Shoot Apical Meristem And Organ Formation, Daniel A. Degennaro
Doctoral Dissertations
Plants are sessile and must adjust their organ growth to their environments. A reservoir of stem cells in the shoot apical meristem (SAM) supplies cells for differentiation into organs. The SAM must balance organ production with stem cell maintenance. The ERECTA family (ERfs) encodes the leucine-rich repeat receptor-like kinases ERECTA (ER), ERECTA-LIKE 1 (ERL1), and ERL2. ERf signaling regulates organ initiation and stem cell maintenance. Results presented in this work include the following:
1) WUSCHEL (WUS) and CLAVATA3 (CLV3) make up a negative feedback loop to maintain SAM size. WUS and CLV3 expression localization is critical for …
Biofabricated Constructs Of Carbon-Based Nanoparticles With Mesenchymal Stem Cells For Orthopedic Repair, Steven D. Newby
Biofabricated Constructs Of Carbon-Based Nanoparticles With Mesenchymal Stem Cells For Orthopedic Repair, Steven D. Newby
Doctoral Dissertations
Breakthroughs in tissue engineering are moving at a rapid rate especially in the regenerative bone biofabrication. Technology growth in the field of additive manufacturing (AM) such 3D bioprinting which provides the ability to create biocompatible 3D construct on which a cell source could be seeded is an encouraging substitute to autologous grafts.
This present research aims to biofabricate a construct for bone tissue engineering using AM technology. The biocompatible material was chosen corresponding to bones extracellular matrix (ECM) composition, which demonstrates an inorganic and organic development phase: Poly (lactic-glycolic acid) was chosen as the polymeric matrix of the compound, due …
