Brief Summary:

Aim of the study:

Evaluation of feasibility, safety and potential effects of stem cells on chronic wounds using a pressure sore model.

Clinical relevance:

  • Accelerated healing of uncomplicated wounds
  • Enhanced healing of complicated (chronic, non-healing) wounds

Study design:

  • Prospective controlled phase I/II study
  • Cohort of 5 patients in pilot study, then reevaluation


- Para- and tetraplegic patients with sacral pressure sores grade III-IVA according to the classification of Daniel and Seiler


1. First surgical intervention:

  • Radical debridement of pressure sore
  • Bone marrow harvest from the iliac crest
  • Isolation of hematopoietic stem cells, aiming to gain > 1 mio. CD 34+ cells per patient under GMP conditions

    3. Stem cell therapy (after 2 days)

  • Injection of stem cells in suspension (50'000 CD 34+ cells in 100 microliter saline per cm2 of wound surface) on one half of the total wound surface and cell-free saline on the other half as a control

    4. Second surgical intervention (after 3-4 weeks):

  • Complete excision of the wound
  • Closure of the defect by fasciocutaneous flap

    5. Evaluation of wound healing:

  • Clinical
  • 3D laser imaging
  • Histology
  • Growth factor assay
