Intrinsic properties of limb bud cells can be differentially reset.
An intrinsic timing mechanism specifies the positional values of the zeugopod (i.e. radius/ulna) and then autopod (i.e. wrist/digits) segments during limb development. Here, we have addressed whether this timing mechanism ensures that patterning events occur only once by grafting GFP-expressing autopod progenitor cells to the earlier host signalling environment of zeugopod progenitor cells. We ...
متن کاملAdolescent anxiety and aggression can be differentially predicted by electrocortical phase reset variables.
Increasing evidence supports the notion that both internalizing (e.g., anxiety) and externalizing (e.g., aggression) behavioral dysregulation are associated with abnormal communication between brain regions. Electroencephalographic (EEG) signals across two electrode sites are said to be coherent with one another when they show consistent phase relations. However, periods of desynchrony with shi...
متن کاملCan Instrumental Value Be Intrinsic? †
In this paper, I critique a common claim that instrumental value is a form of extrinsic value. Instead, I offer an alternative dispositional analysis of instrumental value, which holds that instrumental value can, in certain circumstances, be an example of intrinsic value. It follows, then, that a popular account of the nature of final value—or value as an end—is false: the Moorean identificati...
متن کاملPosition-specific growth of mouse limb bud cells in vitro.
The relationship between cellular position and growth control has been studied in cultures of dissociated fragments of mouse limb bud cells. Using cells derived from various positions along the anterior-posterior axis of the limb bud we have developed culture conditions that optimize growth of positionally isolated cells. Under these conditions limb bud cells display an inherent, position-speci...
متن کاملMaintenance of ZPA signaling in cultured mouse limb bud cells.
The positional signal localized to the posterior (zone of polarizing activity or ZPA) region of the vertebrate limb is transiently expressed during development and a decline in ZPA signaling is accelerated when posterior cells are dissociated and cultured in vitro. The evidence that cultured posterior cells display a precocious decline in ZPA signaling when compared to in vivo studies suggests ...
