Scaffolds for
stem cells
Stem cells are versatile,
unspecialized cells that can be used in combination with a
scaffold for applications such as engineering bone tissue. Nicholas D. Evans, Eileen Gentleman, and Julia M. Polak
Using temporary
functional materials in regenerative medicine has great
potential for reducing the need to replace damaged tissue.
Materials are now being designed that stimulate new tissue
growth while degrading in the body. Julian R. Jones
Fibrous proteins
are finding broad impact in biomaterial systems for a range
of cell and tissue studies because of their unique material
properties. Xianyan Wang, Hyeon Joo Kim, Cheryl Wong, Charu Vepari,
Akira Matsumoto, and David L. Kaplan
The structural organization of biological tissue influences its properties.
The use of scaffolds enables tissue engineers to create
these structural features deliberately. Brett C. Isenberg and Joyce Y. Wong
• Not
seeing is believing
• Particles drive foam-to-powder inversion
• Nanowire fabrication redefined from top to bottom
• The more holey the better
• Tips are more slippery than they seem
• Amyloid mechanics
