In addition to the cell-autonomous effect of Emx2 OE (overexpression), which was nicely shown using the Gfi1Cre driver, could the authors comment on whether there was any non-autonomous effect on re-orienting the hair bundles upon mosaic Emx2 OE driven by Sox2-CreER (i.e. were there any GFP negative hair cells being repolarized)? This would be informative in gauging whether Emx2 had any role in regulating intercellular PCP signaling. It is difficult to see which hair cells are GFP positive in Figure 4F and I. It would be helpful to enhance the signals of the GFP channel. Hair cells in the inner ear convert mechanical stimuli provided by sound waves and head movements into electrical signal.

'Hair Cells' - 2 Article Result(s) For calcium imaging, measurements were made as previously described (Kindt et al., 2012; Zhang et al., 2016). Briefly, larvae were anesthetized with 0.03% 3-amino benzoic acid ethylester (MESAB, Western Chemical, Ferndale, WA) in E3, and mounted with tungsten pins onto a Sylgard recording chamber. Larvae were then microinjected in the heart with 125 μM α-bungarotoxin (Tocris, Bristol, UK) to suppress muscle activity. After paralysis, calcium imaging was performed in extracellular solution in mM: 130 NaCl, 2 KCl, 2 CaCl2, 1 MgCl2 and 10 HEPES, pH 7.3, 290 mOsm. A pressure clamp (HSPC-1, ALA Scientific, New York, NY) attached to a glass pipette (tip diameter ~30–50 μm) was filled with extracellular solution and used to mechanically stimulate HCs along the anterior-posterior axis of the fish. Calcium measurements were made on a Nikon Eclipse NiE microscope using a 60 × 1.0 NA CFI Fluor water-immersion objective and the following filter set: excitation: 480/30 and emission: 535/40. The microscope was equipped with an Orca D2 camera (Hamamatsu, Hamamatsu City, Japan), and images were acquired using Elements software (Nikon Instruments Inc., Melville, NY).

From the tol2 kit, vectors p3E-polyA (301) and pDestTol2CG2 (395), were recombined with p5E-6myosin6b (Kindt et al., 2012), and the middle entry GCaMP6s-CAAX to create Tgmyosin6b:GCaMP6s-CAAX, designated as m6b:GCaMP6s-CAAX. Then, double transgenic fish expressing emx2 and GCaMP6s-CAAX was generated by crossing emx2 gof with Tgmyosin6b:GCaMP6s-CAAX and screened for larvae expressing green HCs (GCaMP6s-CAAX) with mCherry-positive nuclei (emx2).

  5. Cochlear, as well as vestibular, sensory cells are called hair cells because they are characterised by having a cuticular plate with a tuft of stereocilia bathing in the surrounding endolymph. The cell body itself is localised in the perilymph compartment (see transverse section of the organ of Corti). Schematically, both types of cells, inner hair cells (IHCs) and outer hair cells (OHCs), differ by their shape and the pattern of their stereocilia. Their innervation to and from the CNS is also totally different (see ' Organ of Corti: innervation').
  6. For quantification of HC density and surface area in the utricle, a straight A-P line between the two widest points of a given utricle along the anterior-posterior axis was drawn on a stitched confocal image taken at 40x magnification. Two lines perpendicular to the A-P line, marking the middle-third region were drawn and this region was sub-divided into four equal parts marked as 1, 2, 3, and 4 (Figure 4O). Within regions 1 and 3, total number of HCs per 0.01 mm2 and apical surface area of HCs were scored as representatives for the lateral and medial region of the utricle, respectively.

We believe in helping you find the product that is right for you. AliExpress carries wide variety.. Stereocilia bathe in endolymph, which is rich in potassium and characterised by an endocochlear potential of +80 mV, but the hair cell body has a potential between -70 mV and -55 mV. As a result, the electric potential between the endolymph and the hair cell body (between 135 and 150 mV) causes a massive influx of potassium ions from the endolymph to the hair cell when the mechanically-sensitive ion channels open. This cation influx depolarises the hair cell. Based upon experiments in which Emx2 expression is activated at later stages of development it is proposed that Emx2 regulates stereociliary bundle orientation by directing the polarized distribution of Gαi/Par6 relative to the core PCP axis. In these experiments Emx2 is proposed to rapidly alter Gαi or Par6 distribution but occurs too late to alter stereociliary bundle orientation. However, in each figure there are also hair cells with misoriented stereociliary bundles that do not appear to have either a lateral or a medial orientation (blue arrows). Investigating the basis of these hair cells further may provide mechanistic insight.

In a meiosis cell division the number of chromosomes usually reduces by half of its original number. It helps in the production of gametes—sex cells, or sperm and eggs In the human cochlea, there are 3,500 IHCs and about 12,000 OHCs. This number is ridiculously low, when compared to the millions of photo-receptors in the retina or chemo-receptors in the nose! In addition, hair cells share with neurons an inability to proliferate they are differentiated - this means that the final number of hair cells is reached very early in development (around 10 weeks of fetal gestation); from this stage on our cochlea can only lose hair cells.

Potential of Gene and Cell Therapy for Inner Ear Hair Cells

Inner ear hair cells detect sound through deflection of stereocilia, the microvilli-like projections that are arranged in rows of graded heights. Calcium and integrin-binding.. An alternative interpretation raised by this lineage tracing data is that Emx2 functions non-cell autonomously. Perhaps by regulating the expression of a short range secreted factor that is sufficient to initiate all of the cell polarity functions attributed to Emx2. At a minimum, the difference between Emx2Cre lineage tracing and stereociliary bundle orientation should be a point of discussion. Preferably experiments can be conducted to test the autonomy of the Emx2 mutant phenotype or whether this difference is corrected postnatally.With transmission electron microscopy (TEM), the tip link (red arrow) and a lateral link (blue arrow) between medium and tall stereocilia are clearly visible. At both ends of the tip link, a membrane condensation is seen.

We did not observe a change in the size of the maculae or total number of hair cells in mutant utricles. Those results are now in Figure 2—source data 1 and Figure 2—source data 2. Watch the video lecture Hearing: Hair Cells and Semicircular Channels & boost your knowledge! Study for your classes, USMLE, MCAT or MBBS Blocking the Gαi activity with pertussis toxin (Ptx) or knocking out one of the genes that encodes Gαi, Gnai3, can lead to misoriented or reversed hair bundle polarity (Ezan et al., 2013; Tarchini et al., 2013) in cochlear HCs. The polarity-reversal phenotype is rarely observed among cPCP mutants (Montcouquiol et al., 2003; Wang et al., 2005, 2006) but resembles those in the Emx2 mutants. The relocated hair bundle to the same side of the HC in Ptx mutants where the cPCP protein Fz is located, is similar to other epithelial cells in the brain and wing, which we considered to be the default pattern (Strutt, 2001; Vladar et al., 2012; Tree et al., 2002; Boutin et al., 2014; Guirao et al., 2010). The bundle polarity phenotype caused by Ptx suggests that heterotrimeric G proteins are normally required to reverse the kinocilium from its default location in the cochlea. Since cochlear HCs express Emx2 and ectopic Emx2 is capable of affecting Gαi localization independent of the kinocilium (Figure 6N–O”), we hypothesized that Emx2 normally utilizes the Insc/LGN/Gαi complex to change the kinocilium from the default location in cochlear HCs. Under this scenario, Ptx should affect the hair bundle position in macular regions where Emx2 is expressed and may have no effect in the Emx2-negative regions. Additionally, Ptx should block polarity changes induced by ectopic Emx2.

In the original Holley et al. paper it was reported that, in addition to the changes in stereociliary bundle orientation, there was a reduction in the overall area of the sensory epithelia of the saccule. This could be interpreted as evidence that this region of the saccule is specified by Emx2, and as a result is missing in Emx2 mutant thereby yielding a smaller saccule. The authors could address this lingering interpretation of the Holley et al. study, that Emx2 has a role in specification (in addition to or rather than global polarity), by measuring sensory epithelia area for the utricle and saccule in these Emx2 mutant lines. This would be a complement to the EDU experiments already presented.

  3. The rapid component of adaptation arises from the partial closure of the ion channel following the direct fixation of calcium to the channel. The slow component arises from the displacement of myosin along the actin filaments of the stereocilia. This causes the tip link tension to decrease and encourages the channel to close. Here also, the calcium that entered via the mechanically-sensitive ion channel is responsible for activating the myosin.

In our study, we show that Emx2 expression is required to reverse hair bundles from their ‘default’ polarity in the macula and neuromast. Ectopic expression of Emx2 in HCs is sufficient to reverse the ‘default’ bundle polarity. Our loss- and gain-of-function experiments in both inner ear and neuromast indicate that Emx2 is necessary and sufficient to mediate hair bundle orientation in vertebrate HCs.

Organisation of stereocilia

Hair cell stereocilia are at the core of electro-mechanical transduction; the transformation of sound vibration into a neural signal that can be interpreted by the brain. Both types of hair cell have a similar transduction mechanism.The deflection of the stereocilia causes stretch-sensitive ion channels to open. These are non-selectively permeable to cations and are located at the base of the tip links, with 1 or 2 channels per tip link.
