Neural crest stem cells (NCSCs) give rise to the neurons and glia of the peripheral nervous system (PNS). NCSC-like cells can be isolated from multiple peripheral organs and maintained in neurosphere culture. Combining in vitro culture and …

Somatic stem cells are reservoirs to replace lost cells or damaged tissue. Cells with neural stem cell (NSC) characteristics can be isolated from the postnatal mammalian brain into adulthood and expanded as neurospheres. We addressed the ability of these …

Open-chest cardiac injection is the preferred delivery method for cardiac gene and stem cell therapy in small animals, but it is invasive and the operator is unable to see the actual delivery site. High-resolution ultrasound has recently been developed …

The mouse is an important model for the development of therapeutic stem cell/bone marrow cell implantation to treat ischemic myocardium. However, its small heart size hampers accurate implantation into the left ventricular (LV) wall. Precise injections …

We compared therapeutic benefits of intramyocardial injection of unfractionated bone marrow cells (BMCs) versus BMC extract as treatments for myocardial infarction (MI), using closed-chest ultrasound-guided injection at a clinically relevant time post-MI. …

Uniparental parthenotes are considered an unwanted byproduct of in vitro fertilization. In utero parthenote development is severely compromised by defective organogenesis and in particular by defective cardiogenesis. Although developmentally compromised, …

RATIONALE: Although bone marrow endothelial progenitor cell (EPC)-based therapies improve the symptoms in patients with ischemic heart disease, their limited plasticity and decreased function in patients with existing heart disease limit the full benefit …

Photoacoustic (PA) Imaging can estimate the spatial distribution of oxygen saturation (sO2) and total hemoglobin concentration (HbT) in blood, and be co-registered with B-Mode ultrasound images of the surrounding anatomy. This study will focus on the …

The purpose of this paper is to provide the biomedical imaging community with details of a new high resolution contrast imaging approach referred to as “acoustic angiography.” Through the use of dual-frequency ultrasound transducer technology, images …

Porphyrin-phospholipid conjugates were used to create photonic microbubbles (MBs) having a porphyrin shell ("porshe"), and their acoustic and photoacoustic properties were investigated. The inclusion of porphyrin-lipid in the MB shell increased the yield, …
