A look at the cells of different organisms and a comparison of the structures found in plant and animal cells. All animal cells are surrounded by a membrane which contains the cytoplasm. Nearly all ...

Almost eight years ago, Stanford University bioengineer Manu Prakash was looking for a way to watch every cell in an adult living, behaving animal in elaborate detail. He searched the catalog of life ...

Plant stem cells, as in animals, are maintained in specialized microenvironments, which are known as stem cell niches, where local signals from organizer cells act to prevent stem cell differentiation ...

Microfilaments made using a new 3D printing method (gray) form a structure that plant and animal cells (in color) can adhere to. The shapes formed by the filaments determine the uniform cell shapes. A ...
