Liposuction aspirates (primarily saline solution, blood, and adipose tissue fragments) separate into fatty and fluid portions. Cells isolated from the fatty portion are termed processed lipoaspirate (PLA) cells and contain adipose-derived adherent stromal cells (ASCs). Here we define cells isolated from the fluid portion of liposuction aspirates as(More)
AIMS Since the intravascular ultrasound (IVUS) cannot detect neointimal layers in the majority of sirolimus-eluting stents (SES) at the chronic phase, it is still controversial to what extent SES remain uncovered. However, optical coherence tomography (OCT) with excellent resolution may be able to detect thinner neointima. METHODS AND RESULTS A total of(More)
Wound fluids, human serum from platelet-poor and platelet-rich plasma (SPPP and SPRP), contain various soluble factors involved in cell growth and proliferation. Levels of cytokines, chemokines, and matrix metalloproteinases (MMPs) in drainage fluids (DFs) harvested from subcutaneous wounds, punctured fluids (PF) from seroma, and SPPP were measured. SPPP(More)
BACKGROUND Adipose tissue is an easily accessible tissue for use as a soft-tissue filler and source of adult multipotent cells, called adipose-derived stem/stromal/progenitor cells. However, many aspects of its anatomy remain unclear because of the fragile structure of adipocytes and adipose tissue. METHODS Aspirated (n = 15) or intact (n = 9)(More)
CD34 is frequently used as a marker of adipose-derived stem/stromal/progenitor cells (ASCs). However, CD34 expression in human ASCs (hASCs) decreases over time in culture, and the implications of this remain unclear. In this study, we sorted shortly-cultured hASCs into CD34+ and CD34- fractions and compared their biological functions. Results indicated that(More)
BACKGROUND Sirolimus-eluting stents (SES) have incomplete neointimal coverage at 6-month follow up as determined with optical coherence tomography (OCT). The long-term detailed changes of neointima in SES remains to be clarified. METHODS AND RESULTS Serial changes in neointimal coverage of SES from 6 months to 12 months using OCT were examined. Of 21 SES(More)
BACKGROUND Non-invasive measurement of cardiac output (CO) may become an important modality for the treatment of heart failure. Among the several methods proposed, impedance cardiography (ICG) has gained particular attention. There are 2 basic technologies of ICG: thoracic and whole-body ICG whereby the electrodes are applied either to the chest or to the(More)
Injective transfer of autologous aspirated fat is a popular option for soft tissue augmentation, but several issues require attention, including unpredictability and a low survival rate due to partial necrosis. In this study, histologic features and yield of adipose-derived stromal (stem) cells (ASCs) were compared between human aspirated fat and excised(More)
OBJECTIVES This study evaluated the efficacy of catheter-based transcoronary myocardial hypothermia (CTMH) in pigs with acute myocardial ischemia. BACKGROUND Although it has been suggested that hypothermia therapy can attenuate myocardial necrosis, few applications have been accepted for clinical use. METHODS This study comprises 2 substudies. In both(More)
