Abstract Bone healing is orchestrated by multiple cell populations, including those that normally do not produce bone but acquire osteoprogenitor capabilities following injury. Muscle-resident fibroadipogenic progenitors (FAPs) and superficial periosteal cells are among such cells, however their physiologic significance in bone healing and the mechanisms regulating their differentiation are unclear.

I was 38 years old when my brother died suddenly. At the time of his death, I was living in another state more than eight hours away from my family. I will never forget receiving the phone call from my mother — my life forever changed in one brief moment. The feelings of shock and disbelief were overwhelming. I just kept thinking, “If it was just yesterday, he would still be alive.” Dealing with the loss of a sibling has been a learning experience.

Spring has arrived and with the change of season, it can be a difficult time for anyone who has experienced the death of a loved one. Feelings of grief can be devastating and frightening.Grief is a natural response to loss and a very personal and individual experience. How we grieve can be dependent on many factors, including one’s ability to cope, life experiences, faith and the type of loss.
