Spatial pattern formation in chemical and biological systems [PDF]

open access: yes, 1997
One of the central issues in developmental biology is the formation of spatial pattern in the embryo. A number of theories have been proposed to account for this phenomenon.

Ks1, an epithelial cell-specific gene, responds to early signals of head formation in Hydra [PDF]

open access: yes, 1994
As a molecular marker for head specification in Hydra, we have cloned an epithelial cell-specific gene which responds to early signals of head formation.

Mathematical models for somite formation [PDF]

open access: yes, 2007
Somitogenesis is the process of division of the anterior–posterior vertebrate embryonic axis into similar morphological units known as somites. These segments generate the prepattern which guides formation of the vertebrae, ribs and other associated ...

Examination of Fluconazole-Induced Alopecia in an Animal Model and Human Cohort. [PDF]

open access: yes, 2019
Fluconazole-induced alopecia is a significant problem for patients receiving long-term therapy. We evaluated the hair cycle changes of fluconazole in a rat model and investigated potential molecular mechanisms.

An ancestral axial twist explains the contralateral forebrain and the optic chiasm in vertebrates

open access: yes, 2014
Among the best-known facts of the brain are the contralateral visual, auditory, sensational, and motor mappings in the forebrain. How and why did these evolve?

Expression of Distal-less, dachshund, and optomotor blind in Neanthes arenaceodentata (Annelida, Nereididae) does not support homology of appendage-forming mechanisms across the Bilateria [PDF]

open access: yes, 2010
The similarity in the genetic regulation of arthropod and vertebrate appendage formation has been interpreted as the product of a plesiomorphic gene network that was primitively involved in bilaterian appendage development and co-opted to build ...

Microheated substrates for patterning cells and controlling development

open access: yes, 2005
Here, we seek to control cellular development by devising a means through which cells can be subjected to a microheated environment in standard culture conditions.

Development of the human bladder and ureterovesical junction. [PDF]

open access: yes, 2018
The urinary bladder collects urine from the kidneys and stores it until the appropriate moment for voiding. The trigone and ureterovesical junctions are key to bladder function, by allowing one-way passage of urine into the bladder without obstruction ...
