Branching Morphogenesis [PDF]

open access: yesCirculation Research, 2008
Tubular structures are a fundamental anatomic theme recurring in a wide range of animal species. In mammals, tubulogenesis underscores the development of several systems and organs, including the vascular system, the lungs, and the kidneys.

Distinct molecular cues ensure a robust microtubule-dependent nuclear positioning in the Drosophila oocyte

open access: yesNature Communications, 2017
Asymmetric nuclear positioning in the fruit fly oocyte is essential for the correct localization of axis determinants. Here, the authors show that different microtubule-dependent mechanisms contribute to nuclear transport and ensure the robustness of ...

Neurotrophin signaling is a central mechanism of salivary dysfunction after irradiation that disrupts myoepithelial cells

open access: yesnpj Regenerative Medicine, 2023
The mechanisms that prevent regeneration of irradiated (IR) salivary glands remain elusive. Bulk RNAseq of IR versus non-IR human salivary glands showed that neurotrophin signaling is highly disrupted post-radiation.

A method to generate the surface cell layer of the 3D virtual shoot apex from apical initials

open access: yesPlant Methods, 2017
Background The development of cell pattern in the surface cell layer of the shoot apex can be investigated in vivo by use of a time-lapse confocal images, showing naked meristem in 3D in successive times. However, how this layer is originated from apical

Morphogenesis at criticality [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
Significance Biological networks are described by many parameters, and the behavior of a network is qualitatively different (monostable, bistable, oscillating, etc.) in different parts of parameter space. Critical points and surfaces are the borders between such qualitatively different regimes, as with phase transitions in ...

Tissue stiffening coordinates morphogenesis by triggering collective cell migration in vivo

open access: yesNature, 2018
Collective cell migration is essential for morphogenesis, tissue remodelling and cancer invasion. In vivo, groups of cells move in an orchestrated way through tissues.

Loss of the transcription factor RBPJ induces disease-promoting properties in brain pericytes

open access: yesNature Communications, 2019
Pericytes are perivascular cells essential for blood-brain barrier maintenance. Here Diéguez-Hurtado et al. show that depletion of the transcription factor RBPJ in pericytes affects their molecular identity and disturbs endothelial cell behaviour ...

Induction of osteogenesis by bone-targeted Notch activation

open access: yeseLife, 2022
Declining bone mass is associated with aging and osteoporosis, a disease characterized by progressive weakening of the skeleton and increased fracture incidence.

Single-cell transcriptomics reveals functionally specialized vascular endothelium in brain

open access: yeseLife, 2022
The blood-brain barrier (BBB) limits the entry of leukocytes and potentially harmful substances from the circulation into the central nervous system (CNS). While BBB defects are a hallmark of many neurological disorders, the cellular heterogeneity at the

Thyroid hormone receptor knockout prevents the loss of Xenopus tail regeneration capacity at metamorphic climax

open access: yesCell & Bioscience, 2023
Background Animal regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body to full function. Studies in mammals have revealed that many organs lose regenerative ability soon after birth
