Feather regeneration as a model for organogenesis

Feather regeneration as a model for organogenesis.

In the process of organogenesis, different cell types form organized tissues and tissues are integrated into an organ. Most organs form in the developmental stage, but new organs can also form in physiological states or following injuries during adulthood. Feathers are a good model to study post-natal organogenesis because they regenerate episodically under physiological conditions and in respo...

Establishing a new animal model for muscle regeneration studies

Skeletal muscle injuries are one of the most common problems in the worldwide which impose a substantial financial burden to the health care system.  Accordingly, it widely accepted that muscle regeneration is a promising approach that can be used to treat muscle injury patients. However, the underlying mechanisms of muscle regeneration have yet to be elucidated. The muscle structure and muscle...

Bamboo Regeneration via Embryogenesis and Organogenesis

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Biologically-Parameterized Feather Model

Feathers, unlike other cutaneous appendages such as hair, fur, or scales have a definite structure. Variation in feather structure creates a wide range of resulting appearances. Collectively, feather structure determines the appearance of the feather coat, which can largely affect the resulting look of a feathered object (bird). In this paper we define the structure of individual feathers using...
