A Multifunctional 3D Co-Culture System for Studies of Mammary Tissue Morphogenesis and Stem Cell Biology

open access: yesPLoS ONE, 2011
Studies on the stem cell niche and the efficacy of cancer therapeutics require complex multicellular structures and interactions between different cell types and extracellular matrix (ECM) in three dimensional (3D) space. We have engineered a 3D in vitro model of mammary gland that encompasses a defined, porous collagen/hyaluronic acid (HA) scaffold ...

Continuous and intermittent exposure of neonatal rat calvarial cells to PTHrP (1-36) inhibits bone nodule mineralization in vitro by downregulating bone sialoprotein expression via the cAMP signaling pathway [v2; ref status: indexed, http://f1000r.es/18x]

open access: yesF1000Research, 2013
The development and growth of the skeleton in the absence of parathyroid-hormone-related protein (PTHrP) is abnormal.  The shortening of appendicular bones in PTHrP gene null mice is explained by an effect of PTHrP on endochondral bone growth.

Transcriptional regulation of endothelial cell behavior during sprouting angiogenesis

open access: yesNature Communications, 2017
Angiogenesis is a complex process that requires coordinated changes in endothelial cell behavior. Here the authors use Ribo-tag and RNA-Seq to determine temporal profiles of transcriptional activity during postnatal retinal angiogenesis, identifying ...

Unified quantitative characterization of epithelial tissue development

open access: yeseLife, 2015
Understanding the mechanisms regulating development requires a quantitative characterization of cell divisions, rearrangements, cell size and shape changes, and apoptoses.

A selection-based knockout approach for a choanoflagellate reveals regulation of multicellular development by Hippo signaling

open access: yesCell Reports
Summary: Choanoflagellates, the closest living relatives of animals, provide crucial insights into animal origins. The multicellular choanoflagellate Salpingoeca rosetta can be genetically modified, but existing knockout (KO) pipelines are time consuming

Comparative transcriptome analyses of the Drosophila pupal eye

open access: yesG3: Genes, Genomes, Genetics, 2020
Tissue function is dependent on correct cellular organization and behavior. As a result, the identification and study of genes that contribute to tissue morphogenesis is of paramount importance to the fields of cell and developmental biology. Many of the

Live imaging of echinoderm embryos to illuminate evo-devo

open access: yesFrontiers in Cell and Developmental Biology, 2022
Echinoderm embryos have been model systems for cell and developmental biology for over 150 years, in good part because of their optical clarity. Discoveries that shaped our understanding of fertilization, cell division and cell differentiation were only ...

The kinase regulator mob1 acts as a patterning protein for stentor morphogenesis. [PDF]

open access: yesPLoS Biology, 2014
Morphogenesis and pattern formation are vital processes in any organism, whether unicellular or multicellular. But in contrast to the developmental biology of plants and animals, the principles of morphogenesis and pattern formation in single cells ...

Various scenarios of the cell pattern formation in Arabidopsis lateral root

open access: yesActa Societatis Botanicorum Poloniae, 2014
During lateral root (LR) development a coordinate sequence of cell divisions, accompanied by a change of the organ form takes place. Both the order of anatomical events and morphological features may vary for individual primordia.

Cell Differentiation and Replication during Postnatal Development of the Murine First Molar

open access: yesBiology, 2021
Various signaling molecular pathways are involved in odontogenesis to promote cellular replication and differentiation. Tooth formation is controlled mainly by epithelial–mesenchymal interactions.
