Epidermal Cells Expressing Putative Cell Markers in Nonglabrous Skin Existing in Direct Proximity with the Distal End of the Arrector Pili Muscle

open access: yesStem Cells International, 2016
Inconsistent with the view that epidermal stem cells reside randomly spread along the basal layer of the epidermal rete ridges, we found that epidermal cells expressing stem cell markers in nonglabrous skin exist in direct connection with the distal end ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Gloss, colour and grip: multifunctional epidermal cell shapes in bee- and bird-pollinated flowers. [PDF]

open access: yesPLoS ONE, 2014
Flowers bear the function of filters supporting the attraction of pollinators as well as the deterrence of floral antagonists. The effect of epidermal cell shape on the visual display and tactile properties of flowers has been evaluated only recently. In

SWItching On Epidermal Cell Fate [PDF]

open access: yesCell Stem Cell, 2013
Chromatin regulatory complexes are well known regulators of stem cell fate; however, the mechanisms regulating their activity are not well understood. In this issue of Cell Stem Cell, Bao et al. (2013) show that ACTL6a inhibits targeting of the SWI/SNF complex to differentiation genes, thereby preserving the epidermal progenitor state.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Dermal and epidermal cell functions in the growth and regeneration of hair follicles and other skin appendages [PDF]

open access: yes, 1998
Epithelial-mesenchymal interactions are central to the development of skin and skin appendages in vertebrates. These interactions continue throughout adult life and underpin the cyclic growth and loss of hair in mammals. While the molecular basis of such

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

MICROFILAMENTS IN EPIDERMAL CANCER CELLS [PDF]

open access: yesThe Journal of Cell Biology, 1974
The occurrence and structure of microfilaments in epidermal cancers induced in mice by treatment with 3,4-benzpyrene were investigated with the electron microscope. With malignant change, pleomorphic, undifferentiated cells with a cortical zone of microfilaments became increasingly abundant.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

EGF-induced bronchial epithelial cells drive neutrophil chemotactic and anti-apoptotic activity in asthma [PDF]

open access: yes, 2013
Chronic damage and repair of the bronchial epithelium are features of asthma. We have previously reported that ex vivo stimulation of normal bronchial epithelial cells with epidermal growth factor (EGF), a key factor of epithelial repair, enhances the ...
