Mrs Wilks was diagnosed with MS in 2000. Her condition had no treatment or cure and doctors said it would eventually cripple, then kill her.
Mr Wilks, 40, spent hours on the internet searching for alternative treatments and discovered stem cell therapy was being used elsewhere in the world to help slow the progress of diseases such as Parkinson's, cancer and MS.
But the expensive procedure was not yet available in the UK.
The Wilks family were preparing to sell their home to pay for treatment in Holland when colleagues at the Asda store in Huyton stepped in to help, raising more than £13,000.
Stem cells - a controversial therapy
STEM cells are the building blocks for every tissue and organ in the body.
They have the ability to grow outside the body and can be transplanted to produce tissue regrowth in patients with tissue degenerating diseases.
The cells can be taken from a variety of sources, including unborn foetuses - but this makes stem cell therapy controversial because it raises medical ethics issues.
Stem cells used to treat Jan came from umbilical cords which would have otherwise been destroyed.
Her treatment - which took just a few hours - saw cells put into her body via a drip, and an injection into the spine to repair damage.
