While PCD plays a key role in the development and maintenance of multicellular organisms, explaining why single-celled organisms would evolve to actively commit suicide has been far more challenging.
Cell motility is of vital importance for the development and maintenance of multicellular organisms.
A non-conducting function of Kv channels is cell migration [2], [3], [7], [38] which is a critical process in the development and maintenance of multicellular organisms.
Apoptosis plays an important role during development and in the maintenance of multicellular organisms through the removal of damaged, aged, or autoimmune cells [ 6].
Thus, novel assays that evaluate tissue and cell typical bio-markers of thyroid hormone and EDC action in development and maintenance of healthy organisms are urgently needed.
Cell migration is a central process in the development and maintenance of multicellular organisms and controls biological processes such as embryonic development, wound healing, immune responses, tumor formation, and metastasis.
This ability is necessary in many situations, ranging from embryonic development to the maintenance of mature organisms, and its deregulation is a hallmark of cancer [ 1] and many other diseases [ 2].
Future studies are clearly necessary to accumulate more data in the hope that the sheer quantity of information will inevitably result in a qualitative change in our understanding of how individual cells use their cell-cell adhesion structures to coordinate their behavior in building and homeostatic maintenance of multicellular organisms.
Despite the ubiquity of such mutualistic associations and their importance to health and the environment, studies of many host-associated microorganisms have been complicated by difficulties in both the maintenance of symbiotic organisms in culture and the inability to genetically manipulate them.
With the increasing complexity of higher organisms, cells had to evolve diverse mechanisms to exchange spatial and temporal information crucial for tissue organization and the maintenance of the organism as a whole.
