In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. [3]
Cell and Tissue Research presents regular articles and reviews in the areas of molecular, cell, stem cell biology and tissue engineering.In particular, the journal provides a forum for publishing data that analyze the supracellular, integrative actions of gene products and their impact on the formation of tissue structure and function.
“The concentrations we saw in the brain tissue of normal individuals, who had an average age of around 45 or 50 years old, were 4,800 micrograms per gram, or 0.48% by weight,” Campen said.
There’s no single test to assess biological aging, but the two used in the current study are: ... By closely examining the methylation in specific cells or tissues, epigenetic clocks can ...
The brain may contain higher -- and more significant -- amounts of microplastics than other organs in the body, according to a new study. Researchers from the University of New Mexico Health ...
Their function is to give shape and tension to cells and tissues and they are also the site of cell-cell signaling. Adherens junctions are made of cell adhesion molecules from the cadherin family. There are over 100 types of cadherins, corresponding to the many different types of cells and tissues with varying anchoring needs.

Centre of the Cell online; The Image & Video Library of The American Society for Cell Biology Archived 2011-06-10 at the Wayback Machine, a collection of peer-reviewed still images, video clips and digital books that illustrate the structure, function and biology of the cell.
"All biology is comprised of organic compounds. The origin of life is related to organic chemistry, some of which is preserved in these rocks from 4.5 billion years ago," said astrobiologist and ...
