Have any scientists publically expressed belief-in or support-for cryonics ?
Yes. See Scientists’ Open Letter on Cryonics in which over 60 eminent scientists affirm that “cryonics is a legitimate science-based endeavor”. Note that cryonics is science-based, but cannot correctly be called current science. Cryonics is a protoscience based on expectations of the vitrification and repair capabilities of future science. Although the projection is less, possible human habitation of Mars is similarly a science-based concept based on projections of the capabilities of current science.
