The new shares issue also includes a penalty payment of £172,500.
In total, WideCells issued 115mln new shares to repay £287,500 owed to the investor as part of a financing deal reached with previous management last September.
The European High Growth Opportunities Securitization Fund now owns 28.6% of WideCells’ shares. It has previously built up and sold down its holdings.
The conversion comes at a time of change for WideCells, with the recent appointment of David Sefton as its executive chairman, meaning it is likely to pivot away from stem cells.
WideCells shares were broadly flat at 0.47p on Thursday.
