We can regenerate! Researchers reveal our ribs regrow if damaged - and say the same could be true for our entire skeleton


comments

While we may not quite have the regenerative powers of a superhero, humans are surprisingly adept at regrowing ribs, researchers have found.

Researchers have analysed the capabilities in mice after spotting a human subject who was able to regrow part of a rib.

The team found that mice and humans were able to regrow removed ribs within months.  

The team found that mice and humans were able to regrow removed ribs within months - and could be used in treating osteoporosis and other skeletal disorders.

WHY DO WE HAVE RIBS?

The function of ribs is threefold. 

First, they provide protection for the lungs and heart, forming a 'cage' around them.

Second, they are one of the few bones that continue to make red marrow (and thus blood cells) in adults.

They also serve as attachment points for chest muscles involved in respiration.

In a new study in the Journal of Bone and Mineral Research, a team directed by USC Stem Cell researcher Francesca Mariani studied the phenomenon.  

Using CT imaging, the team monitored the healing of a human rib that had been partially removed by a surgeon.

The eight centimeters of missing bone and one centimeter of missing cartilage did partially repair after six months.

To better understand this repair process, they removed sections of rib cartilage — ranging from three to five millimeters — from a related mammal, mice. 

When they removed both rib cartilage and its surrounding sheath of tissue — called the 'perichondrium,' the missing sections failed to repair even after nine months. 

However, when they removed rib cartilage but left its perichondrium, the missing sections entirely repaired within one to two months.

The researcher could lead to new therapies for skeletal regeneration elsewhere in the body

They also found that a perichondrium retains the ability to produce cartilage even when disconnected from the rib and displaced into nearby muscle tissue — further suggesting that the perichondrium contains progenitor or stem cells.

'We believe that the development of this model in the mouse is important for making progress in the field of skeletal repair, where an acute clinical need is present for ameliorating skeletal injury, chronic osteoarthritis and the severe problems associated with reconstructive surgery,' said Mariani, assistant professor of Cell and Neurobiology and principal investigator in the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC. 

'At the early stages in our understanding, the mouse provides us with an exceptional ability to make progress, and we are excited about the potential for using cells derived from the rib perichondrium or using rib perichondrium-like cells for regenerative therapy.'

  9. I'm recommending Dr ohunyom to everyone who have herpes simplex virus to get the cure from him. I was diagnose of genital herpes in 2019 and i have been searching and asking questions to see if i could get something to cure the disease because i did not believe what the doctors say that no cure is found yet. I came across a comment on Youtube and the person testify how she was cured from herpes and hpv after using Dr ohunyom herbal medicine. I quickly contact Dr ohunyom and explain my problem to him and he prepare the herbs and send it to me through UPS and gave me instructions on how to use it and tell me to go for checkup after usage which i did after two weeks of taken the herbal medicine and my result was NEGATIVE. I waited another month and retested the result was still NEGATIVE and my doctor told me that am completely free from herpes. Am so happy and grateful to Dr ohunyom for what he has done for me and i will continue to share this for people out there to know that there is cure for herpes. You can contact Dr ohunyom on email and WhatsApp to get the cure from him. Email: drohunyom@gmail.com and WhatsApp +2349060579973 he can fix this.HIV.HEPATITIS.ANTHRAX.HPV.CANCER.ALSAND ALSO SOLVE YOUR RELATIONSHIP PROBLEM
