To investigate whether bone marrow cells migrate and are engrafted into the olfactory epithelium and differentiate into olfactory neurons, bone marrow cells of green fluorescence protein (GFP) mice were transplanted into lethally irradiated recipient mice. Immunohistochemical staining was performed to evaluate the engraftment of donor bone marrow cells into(More)
CONCLUSION Notch signaling pathway may play an important role in the development of the olfactory epithelium (OE). Objectives. To elucidate whether the Notch signaling pathway mediates the developmental processes in the developing OE. MATERIALS AND METHODS The expression of Notch1 and Hes5 in the developing OE of mice with ages ranging from embryonic day(More)
CONCLUSION Bone marrow-derived cells can be engrafted in the olfactory bulb and a few cells can differentiate into mitral/tufted cells in the olfactory bulb. OBJECTIVES To investigate whether bone marrow-derived cells can be engrafted into the olfactory bulb and differentiate into neurons and glial cells after methimazole administration. METHODS Bone(More)
CONCLUSIONS The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome plays an important role in the pathogenesis of middle ear diseases. Modulation of inflammasome-mediated inflammation may be a novel therapeutic strategy for cholesteatoma and chronic otitis media. OBJECTIVE NLRP3 inflammasome is a critical molecule(More)
OBJECTIVES To study whether cyclooxygenase 2 (COX-2) plays a role in the development of otitis media with effusion (OME). STUDY DESIGN/METHODS An experimental model of endotoxin-induced OME was used in healthy BALB/c mice. Solutions of Salmonella typhimurium endotoxin were injected into the middle ears of the mice, and COX-2 expression in the middle ears(More)
Tympanoplasty operations to improve hearing impairment require a wide middle ear cavity and reconstruction of columellar formations. There is no specific material for use in the reconstruction of columellar formations. Tissue response to BMP has been employed as regenerative material. To our knowledge, however, there are no reports of the reconstruction of(More)
BACKGROUND Although it is well known that olfactory receptor neurons differentiated from stem cells have an unusual lifelong ability to continue neurogenesis, effective treatment of patients with sensorineural olfactory loss is still lacking. The purpose of this study was to determine whether intranasal prolactin (PRL) is an effective inducer of(More)
The Notch signaling pathway is an evolutionary conserved mechanism that plays an important role in cell-cell communication and cell fate in a wide range of tissues. The mammalian family of Notch receptors consists of 4 members: Notch1/2/3/4. The Notch ligand family consists of 5 members: Delta1/3/4 and Jagged1/2. Math1 encodes a murine basic(More)
To investigate whether bone marrow-derived cells (BMC) would migrate and engraft into the sensory epithelium of the inner ear, BMC of green fluorescence protein (GFP) mice were transplanted into lethally irradiated recipient mice. Then the recipient mice were treated with streptomycin and immunohistochemical staining was performed to evaluate the migration(More)
The mac-1 gene of Myxococcus xanthus TA, an antibiotic TA producer, encoded a protein with strong sequence similarity to the antibiotic ATP-binding cassette (ABC) transporter for macrolide antibiotics. The mac-1 gene encoding protein (Mac-1) had two ATP-binding domains containing Walker A and B motifs, and no hydrophobic transmembrane regions. Insertional(More)
