Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

5.0K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Whole Body Regeneration01:33

Whole Body Regeneration

4.0K
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

1.5K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

4.5K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Area of Science:

  • Muscle regeneration research
  • Orofacial development
  • Skeletal muscle biology

Background:

  • Orofacial congenital defects, such as cleft lip/palate, and trauma result in poor muscle regeneration and fibrosis.
  • Orofacial muscles (tongue, branchiomeric) are crucial for chewing, swallowing, and speech.

Purpose of the Study:

  • To review and compare orofacial muscle development and regeneration with trunk and limb muscles.
  • To identify strategies for enhancing orofacial muscle repair and reducing fibrosis.

Main Methods:

  • Comparative analysis of molecular regulation in orofacial vs. other skeletal muscles.
  • Review of current knowledge on muscle development and regeneration pathways.

Main Results:

  • Orofacial muscle development differs molecularly from trunk/limb muscles.
  • Orofacial muscles exhibit lower regenerative capacity and increased fibrosis post-injury.

Conclusions:

  • Targeted approaches are needed to stimulate orofacial muscle regeneration.
  • Growth factors (e.g., FGF, HGF) and TGFβ1 pathway inhibition can improve outcomes.
  • Combined strategies offer promising advancements for surgical treatment of orofacial muscle defects.
