Summary
Researchers found an actin-shell surrounding Xenopus yolk platelets using DNase I. This actin-shell may distinguish between autosynthetic and heterosynthetic eggs in Xenopus development.
Area of Science:
- Developmental Biology
- Cell Biology
- Biochemistry
Background:
- Previous immunofluorescence studies indicated a potential actin covering around Xenopus yolk platelets.
- This suggested structure was termed the 'actin-shell'.
- The precise nature and function of this actin-shell remained to be elucidated.
Purpose of the Study:
- To definitively demonstrate the existence of the actin-shell around Xenopus yolk platelets.
- To investigate the potential functional significance of the actin-shell in early development.
Main Methods:
- Utilized a DNase I-fluorochrome complex for high-resolution imaging.
- Applied immunofluorescence techniques to visualize actin localization.
Main Results:
- Clearly demonstrated the presence of an actin-shell surrounding Xenopus yolk platelets.
- Provided strong evidence for the actin-shell structure previously hypothesized.
Conclusions:
- The actin-shell is a confirmed structure associated with Xenopus yolk platelets.
- The presence of the actin-shell may serve as a key differentiator between autosynthetic and heterosynthetic egg types.

8.5K
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

01:31Mechanism of Lamellipodia Formation
3.4K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

01:10The Role of Actin and Myosin in Non-muscle Cells
4.4K
Actin and myosin or actomyosin filaments also play a significant role in cells other than those involved in muscle contraction (which occurs within the sarcomere of muscle cells). The mechanism of non-muscle cell contractile bundles was first observed in Dictyostelium and Acanthamoeba. In non-muscle cells, two bundles are commonly found: stress fibers and actomyosin adherence belts. These contractile bundles are smaller and less organized than the ones found in muscle cells. They are held...

01:26Introduction to Actin
6.2K
Actin is a highly conserved cytoskeletal protein found abundantly in eukaryotic cells. It constitutes 10% weight of the total cellular protein in muscle cells, while in non-muscle cells, it is lower and makes up around 1–5 percent of the total cell protein. Actin found in the unicellular amoebae and complex multicellular animals is around 80% similar, demonstrating their conservation over a billion years of evolution. Actin coding genes are conserved within species and across...

01:16Cell Motility through Blebbing
2.3K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.
