"Briar has had her stem-cell treatment, which went well.
"She has now emerged from 10 days in isolation which Briar said went quickly," Cherry Novis said.
"While in isolation only staff are allowed into her room. She is now allowed visitors and out into the lounge as long as she wears a mask. Her immune system is gradually building up and today she has one final infusion before we leave Moscow on Tuesday for our flights home."
Once they return from Russia, Briar will be in isolation in her home for up to three months so people will not be able to visit her for some time.
Cherry Novis said it had been an emotional and stressful journey with many happy moments for their family.

Over months of fundraising events as well as a Givealittle page, the family managed to raise $80,000 for the Russia trip.
It was less than the initial target of $95,000 but it was enough for the cost of the treatment, which was about $77,000.
