Dynamics of cell-type transition mediated by epigenetic modifications [PDF]
Maintaining tissue homeostasis requires appropriate regulation of stem cell differentiation. The Waddington landscape posits that gene circuits in a cell form a potential landscape of different cell types, wherein cells follow attractors of the probability landscape to develop into distinct cell types.

Tip cell overtaking occurs as a side effect of sprouting in computational models of angiogenesis [PDF]
During angiogenesis, endothelial cells compete for the tip position during angiogenesis: a phenomenon named tip cell overtaking. It is still unclear to what extent tip cell overtaking is a side effect of sprouting or to what extent a biological function.

Tractions and stress fibers control cell shape and rearrangements in collective cell migration [PDF]
Key to collective cell migration is the ability of cells to rearrange their position with respect to their neighbors. Recent theory and experiments demonstrated that cellular rearrangements are facilitated by cell shape, with cells having more elongated shapes and greater perimeters more easily sliding past their neighbors within the cell layer. Though

Langerhans cells: an update [PDF]
SummaryLangerhans cells belong to the family of dendritic cells, professional antigen‐presenting cells, and populate the skin and epithelia of mammals. It was the extensive investigation of this particular dendritic cell subpopulation in earlier days, which contributed crucially to the current understanding of the regulation of antigen processing and ...

Abstract Background CD163 is a scavenger receptor predominantly expressed on the surfaces of macrophages in various mammalian species and is a marker of anti‐inflammatory (M2‐like) macrophages. High density of CD163‐positive tumor‐associated macrophages (TAMs) is associated with worse prognosis in various patient tumors.

Are physiological oscillations physiological?
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Indeterminate Cell Histiocytosis: A Case Report
Indeterminate cell histiocytosis is a rare neoplasm composed of cells with mixed characteristics of Langerhans cells and non-Langerhans cells. An otherwise healthy, 36-year-old woman presented with asymptomatic generalized papules and nodules that had ...

Recurrent Indeterminate Dendritic Cell Tumor of the Skin [PDF]
Indeterminate dendritic cell tumor (IDCT) is a dendritic cell tumor that displays histologic features similar to those of Langerhans cells. The origin of the indeterminate cells may represent precursors of Langerhans cells or skin dendritic cells.

Langerhans cell histiocytosis (LCH) is a group of rare disorders histologically characterized by the proliferation of Langerhans cells. Multiple organs and systems may be involved by the disease. Typically, there is bone involvement and, less frequently, lesions may be found in the lungs, liver, lymph nodes, skin, and mucosa.

Diagnóstico precoce de histiocitose das células de Langerhans: relato de caso [PDF]
Langerhans' cells histiocytosis is a disease that belongs to the group of histiocytic disorders and is considered a rare pathology. It results from a proliferation and accumulation of cells of the phagocytic mononuclear system, including Langerhans ...
