Oxygen changes drive non-uniform scaling in Drosophila melanogaster embryogenesis [version 1; referees: 2 approved, 1 approved with reservations]

open access: yesF1000Research, 2015
We previously demonstrated that, while changes in temperature produce dramatic shifts in the time elapsed during Drosophila melanogaster embryogenesis, the relative timing of events within embryogenesis does not change.

A Conserved Cell Growth Cycle Can Account for the Environmental Stress Responses of Divergent Eukaryotes [PDF]

open access: yes, 2012
The respiratory metabolic cycle in budding yeast (Saccharomyces cerevisiae) consists of two phases most simply defined phenomenologically: low oxygen consumption (LOC) and high oxygen consumption (HOC).

Aspects of tissue morphogenesis and organisation in the zebra fish, Brachydanio rerio [PDF]

open access: yes, 2015
This thesis is mainly concerned with the impact of cellular mechanisms which influence a particular instance of tissue morphogenesis, namely development of the caudal fin of the zebra fish, Brachydanio rerio.

LocalZProjector and DeProj: a toolbox for local 2D projection and accurate morphometrics of large 3D microscopy images

open access: yesBMC Biology, 2021
Background Quantitative imaging of epithelial tissues requires bioimage analysis tools that are widely applicable and accurate. In the case of imaging 3D tissues, a common preprocessing step consists of projecting the acquired 3D volume on a 2D plane ...

Human Intestinal Morphogenesis Controlled by Transepithelial Morphogen Gradient and Flow-Dependent Physical Cues in a Microengineered Gut-on-a-Chip

open access: yesiScience, 2019
Summary: We leveraged a human gut-on-a-chip (Gut Chip) microdevice that enables independent control of fluid flow and mechanical deformations to explore how physical cues and morphogen gradients influence intestinal morphogenesis.

Brain-specific lipoprotein receptors interact with astrocyte derived apolipoprotein and mediate neuron-glia lipid shuttling

open access: yesNature Communications, 2021
Lipophorin receptors (LpRs) regulate structural and functional development of neurons in Drosophila. Here authors demonstrate how short isoforms of LpR1 mediates astrocyte lipid shuttling to neuron through interacting with glia lipoprotein GLaz and the ...

Evidence of a possible multicellular life cycle in Escherichia coli

open access: yesiScience, 2023
Summary: Biofilms are surface-attached multicellular microbial communities. Their genetics have been extensively studied, but the cell-scale morphogenetic events of their formation are largely unknown.

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 ...

Lymphatic vascular morphogenesis in development, physiology, and disease [PDF]

open access: yes, 2011
The lymphatic vasculature constitutes a highly specialized part of the vascular system that is essential for the maintenance of interstitial fluid balance, uptake of dietary fat, and immune response. Recently, there has been an increased awareness of the

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.
