For fantasy, horror, and science fiction stories in podcast form, PodCastle (podcastle.org), PseudoPod
(pseudo pod.org), and Escape Pod (escapepod.org) employ excellent voice actors to provide a range of fictional audio content under the Escape Artists Podcast Network.
The growth pattern of DFSP resembles that of fibroblasts with pseudopod
like extensions from a central mass that penetrate tissue over a time.
Activation of platelets initiates the deformation of the cells with pseudopod
formation and ends with blood coagulation or thrombus formation .
Mesenchymal movement encompasses a five-step migration cycle characterized by pseudopod
protrusion at the leading edge, formation of focal contacts, focalized proteolysis, actomyosin contraction, and detachment of the trailing edge [as reviewed in ].
PA has a pseudopod
like extension into adjacent tissue and this is why it should be performed an adequate excision of the tumor with clear margins, so there would be no recurrence .
The development of foot (pseudopod
), anterior adductor muscle and gill rudiment were observed in the shell but not function yet in this stage (Fig.
The driving force for cell migration is provided by actin cytoskeleton polymerization, which induces membrane protrusion and pseudopod
formation (Saarikangas et al.
James Cameron recalls working side-by-side on set with Knoll to create the pseudopod
for The Abyss.
Video microscopy of the cell detachment process appeared to indicate the release of individual pseudopod
tethers, similar to what had been described for release or thinning of astrocyte cell processes induced by thrombin agonist [38,41].
The ability of [Ca.sup.2+] to control the assembly and disassembly of the platelet cytoskeleton provides a mechanism for cytoskeletal involvement in shape change and pseudopod
formation during platelet activation .
(1) In The Abyss (1989) an alien pseudopod
snakes around a deep-sea research facility searching for the protagonist.
One possibility, Li says, is that forming a pseudopod
leaves a temporary "sear" in the cell's structure, making it more likely that the next pseudopod
will emerge from a different part of the organism's cell wall and head in a different direction.
