BACKGROUND Fat grafting is promising, but clinical outcomes are not always predictable. The mechanisms of tissue revascularization/regeneration, and tissue necrosis and subsequent absorption/fibrosis of the graft, are poorly understood. METHODS An autologous inguinal fat pad was transplanted under the scalp of mice, and detailed cellular events during the(More)
BACKGROUND Fat grafting is a promising modality for soft-tissue augmentation/reconstruction. However, grafted fat tissue is not initially perfused and relies on plasmatic diffusion from the recipient bed until revascularization occurs. The authors evaluated the therapeutic effects of normobaric hyperoxygenation for enhancing fat graft retention. METHODS(More)
BACKGROUND Hyaluronic acid (HA) fillers have become the most popular tool for wrinkle treatment and volumization, although HA is generally absorbed within 6-12 months and requires repeated treatments to maintain the effects. METHODS HA was injected onto the bone for volumization with a small 30-gauge needle to examine the long-lasting effects. Of the 63(More)
UNLABELLED Three-dimensional culture of mesenchymal stem/stromal cells for spheroid formation is known to enhance their therapeutic potential for regenerative medicine. Spheroids were prepared by culturing human adipose-derived stem/stromal cells (hASCs) in a non-cross-linked hyaluronic acid (HA) gel and compared with dissociated hASCs and hASC spheroids(More)
Adipose tissue (AT) is composed of mature adipocytes and stromal vascular fraction (SVF) cells, including adipose stem/stromal cells (ASCs). We characterized hematopoietic cells residing in human nonobese AT by analyzing the SVF isolated from human lipoaspirates and peripheral blood (PB). Flow cytometry revealed that AT-resident hematopoietic cells(More)
Multipotent stem/progenitor cells localize perivascularly in many organs and vessel walls. These tissue-resident stem/progenitor cells differentiate into vascular endothelial cells, pericytes, and other mesenchymal lineages, and participate in physiological maintenance and repair of vasculatures. In this study, we characterized stromal vascular cells(More)
Stage-specific embryonic antigen-3 (SSEA-3)-positive multipotent mesenchymal cells (multilineage differentiating stress-enduring [Muse] cells) were isolated from cultured human adipose tissue-derived stem/stromal cells (hASCs) and characterized, and their therapeutic potential for treating diabetic skin ulcers was evaluated. Cultured hASCs were separated(More)
BACKGROUND AIMS Adipose-derived stem/progenitor cells (ASCs) are typically obtained from the lipoaspirates; however, a smaller number of ASCs can be isolated without enzymatic digestion from the infranatant liposuction aspirate fluid (LAF). We evaluated the effectiveness of an adherent column, currently used to isolate mesenchymal stromal cells from bone(More)
Although various injection techniques of hyaluronic acid (HA) filler for facial rejuvenation have been developed, correction of deep wrinkles/grooves, such as the nasolabial fold (NLF), with intradermal or subdermal injections remains difficult. We tested the intradermal HA injection method to place multiple HA struts by (1) inserting a small needle(More)
BACKGROUND Despite the clinical potential of adipose-derived stem/stromal cells (ASCs), there are some clinical difficulties due to the regulation of cell therapies. MATERIALS & METHODS Micronized cellular adipose matrix (MCAM) injectable was prepared through selective extraction of connective tissue fractions in fat tissue only through mechanical minimal(More)
