Abdominal pain is a common symptom associated with irritable bowel syndrome and inflammatory bowel diseases(IBDs),affecting about 20%of the global population(Grundy et al.,2019).Current pain therapies are poorly effective on visceral pain of intestinal origin and present several side effects,hence the need to identify novel molecular and cellular targets for drug development.

In pat i e nt s,a s well as in animal mod e l s,hypersensitivity to external stimuli(hyperalgesia and allodynia)or spontaneous pain is often the first,and the most disabling,symptom of neuropathy(Davis et al.,2020).The increased activity of sensitive neurons drives pain development,making ion channel modulation a fundamental target for current pharmacotherapy as well as one of the most investigated by the R&D departments of pharmaceutical companies(Bennett et al.,2019).

Unlike emotions, which are short-lasting events accompanied by viscero-motor responses, vitality forms are continuous internal states that modulate the motor behaviors of individuals and are devoid of the autonomic modifications that characterize real emotions. Despite the importance of vitality forms in social life, only recently have neurophysiological studies been devoted to this issue. The first part of this review describes f MRI experiments, showing that the dorso-central insula is activated during the execution, the perception and the imagination of arm actions endowed with different vitality forms as well as during the hearing and the production of speech conveying vitality forms. In the second part, we address the means by which the dorso-central insula modulates the networks for controlling action execution and how the sensory and interoceptive information is conveyed to this insular sector. Finally, we present behavioral data showing the importance of vitality forms in social interactions.

Chronic pain is sustained by a phenomenon of hyper-activation of nociceptive neurons both at peripheral(peripheral sensitization)and central(central sensitization)*** onset and maintenance of pain,however,is to be found in the interaction among the various cell populations in the nervous tissue including neurons and glia(Nam et al.,2016).The pathogenesis of neuropathic pain is extremely complex depending on the primary cause of nerve damage,*** nerve injury is associated with a robust inflammatory response while chemotherapy-induced pain is characterized by a modest phlogistic component(di cesare Mannelli et al.,2013).Despite these differences,a powerful common concept to explain the cellular mechanisms underlying pain is the activation of glia.

History and biology of mesenchymal stem cell (MSC): MSCs were firstly described around 1970s by Friedenstein and his collaborators as a subpopulation of colony forming, clonogenic, plastic adherent stromal bone marrow derived cells, with the capacity to regenerate other tissues (Murphy et al., 2013). Caplan (1991) proposed that these mesenchymal cells were “stem” because of their ability to differentiate to any lineage of mesodermal cells. The richest sources of MSCs are bone marrow and adipose tissue, but they can also be isolated from synovial fluid, periosteum, fetal organs, placenta, umbilical cord blood and amniotic fluid (Murphy et al., 2013;Sherman et al., 2015).
