In this urgent search for a 'new normal', the embodied of hosting such an unwelcomed virus, the philosophical questions this raises, and the tourism futures already in the making, have not been fully explored. The article introduces Nancy's (2000/2002) philosophy, [The Intruder], where he reflects on having a heart transplant operation to give body to the experiences of the self exteriority and of otherness always already within.

Final results of a phase I-II trial using ex vivo expanded autologous Mesenchymal Stromal Cells for the treatment of osteoarthritis of the knee confirming safety and suggesting cartilage regeneration.

Background: Cellular therapies have shown encouraging results in the treatment of chronic osteoarthritis (OA). Herein, we present the final results of a phase I-II clinical trial assessing the feasibility, safety and efficacy of ex vivo expanded autologous bone marrow Mesenchymal Stromal Cells (MSC, XCEL-M-ALPHA), infused intra-articularly, in patients with knee OA.

Methods: Fifteen patients (median age=52years) with grade II(9) or III(6) gonarthrosis (Kellgren & Lawrence classification) and chronic pain were treated with an intra-articular infusion of 40.
