One of diabetes' most dangerous complications
Quick answer
Diabetic foot ulcers are notoriously hard to heal, prone to spreading infection and sepsis, and in severe cases lead to toe or ankle amputation. EHL Bio reports using stem cells to help ulcers close and preserve foot function, showing wound progression before treatment and after the 1st, 2nd and 5th doses. The proposed mechanism is new capillary formation plus reduced chronic inflammation in the wound bed.
Diabetic ulcers arise from peripheral neuropathy (so injuries go unfelt), peripheral arterial disease (poor perfusion) and impaired immunity — turning a small wound chronic within weeks.
Standard care always comes first: glucose control, debridement, offloading with specialist footwear or casting, infection control, and vascular assessment to decide whether revascularisation is needed.
Cell therapy is positioned as an adjunct where a wound will not close despite full standard care. Global evidence is mixed across peri-wound cell injection, cell-seeded dressings and growth factor products, with outcomes tracking the patient's vascular status.
What genuinely saves limbs is daily foot inspection and immediate medical review at any wound, redness or unusual odour — a delay of days can turn a healable ulcer into limb loss.
Very superficial wounds may heal with good glucose control and no infection, but deep or necrotic wounds always need medical care.
Very much so. Without adequate perfusion, no cell or drug closes the wound; revascularisation may be required first.
Generally infection must be controlled first; adjunctive therapy to speed closure comes afterwards.
Pressure-offloading footwear, daily foot checks, correct nail care and regular diabetic foot clinic follow-up.
