Companion Blood Cells Control Ovarian Stem Cell Niche Microenvironment and Homeostasis [PDF]
Cell Reports, 2015 The extracellular matrix plays an essential role for stem cell differentiation and niche homeostasis. Yet, the origin and mechanism of assembly of the stem cell niche microenvironment remain poorly characterized.

A pocket companion to cell-free DNA (cfDNA) preanalytics [PDF]
Tumor Biology, 2023 The cumulative pool of cell-free DNA (cfDNA) molecules within bodily fluids represents a highly dense and multidimensional information repository. This “biological mirror” provides real-time insights into the composition, function, and dynamics of the diverse genomes within the body, enabling significant advancements in personalized molecular medicine.

Characterization of companion animal pluripotent stem cells [PDF]
Cytometry Part A, 2017 AbstractPluripotent stem cells have the capacity to grow indefinitely in culture and differentiate into derivatives of the three germ layers. These properties underpin their potential to be used in regenerative medicine. Originally derived from early embryos, pluripotent stem cells can now be derived by reprogramming an adult cell back to a pluripotent

Companion cells: a diamond in the rough [PDF]
Journal of Experimental Botany, 2016 Vascular plants have developed highly specialized cells to transport nutrients and developmental signals. The differentiation process includes the degradation of multiple organelles of the sieve element cells (SEs) to facilitate transport and, as a consequence, SEs become dependent on neighboring companion cells (CCs). Despite its importance for phloem

Vagrant Stem Cells Draft Their Gene Companions [PDF]
Cell Stem Cell, 2010 In a recent issue of Nature Medicine, Ryan et al. (2010) uncover genetic modifiers of G-CSF responses by hematopoietic progenitors. The authors document a negative role of EGFR signaling and, provided an analogous pathway functions in humans, propose a potential new angle to promote clinical blood stem cell mobilization.

The Crucial Roles of Phloem Companion Cells in Response to Phosphorus Deficiency. [PDF]
Plant Cell EnvironABSTRACTMineral deficiency is a major problem in agriculture. Plant adaption to low mineral environments involves signaling between shoots and roots, via the food transport cells, the sieve elements. However, due to the sequestered position of the sieve elements in the vascular bundles, identifying shoot‐to‐root mobile signals is challenging.

The companions: regulatory T cells and gene therapy [PDF]
Immunology, 2009 SummaryUndesired immunological responses to products of therapeutic gene replacement have been obstacles to successful gene therapy. Understanding such responses of the host immune system to achieve immunological tolerance to a transferred gene product is therefore crucial.

Differential Distribution of Proteins Expressed in Companion Cells in the Sieve Element-Companion Cell Complex of Rice Plants [PDF]
Plant and Cell Physiology, 2005 Sieve tubes are comprised of sieve elements, enucleated cells that are incapable of RNA and protein synthesis. The proteins in sieve elements are supplied from the neighboring companion cells through plasmodesmata. In rice plants, it was unclear whether or not all proteins produced in companion cells had the same distribution pattern in the sieve ...

Plasmodesmatal frequency in relation to short-distance transport and phloem loading in leaves of barley (Hordeum vulgare). Phloem is not loaded directly from the symplast [PDF]
, 1997 We investigated the phloem loading pathway in barley, by determining plasmodesmatal frequencies at the electron microscope level for both intermediate and small blade bundles of mature barley leaves.
