Background
Globally, nearly 300 million people suffer from hearing impairment caused by genetic abnormalities, traumatic noise exposure, age-linked deterioration, or ototoxic agents. This sensory disorder imposes profound societal costs, degrading cognitive performance, occupational efficiency, and overall well-being. Modern interventions are restricted to assistive technologies such as cochlear implants and hearing aids, which merely augment rather than biologically restore hearing. Inner ear organoid models now serve as transformative tools for advancing therapeutic discovery, enabling precision gene editing for hereditary conditions and high-throughput drug evaluation to regenerate auditory hair cells. Nevertheless, inconsistencies in organoid maturation due to variable differentiation protocols constrain their reproducibility in translational applications.

The cochlea, a coiled sensory organ crucial for auditory processing, features three interconnected fluid chambers within the inner ear: the scala vestibuli, scala media (cochlear duct), and scala tympani. Reissner's membrane and the basilar membrane structurally partition these compartments. Perilymph occupies the upper and lower chambers, while potassium-enriched endolymph fills the central duct. Along the scala media's lateral boundary lies the stria vascularis—a vascularized epithelium responsible for maintaining endolymphatic ion homeostasis through regulated potassium secretion and endothelin production. Resting on the basilar membrane, the organ of Corti houses mechanosensory cells, including three parallel rows of outer hair cells (OHCs) and a single inner hair cell (IHC) row, alongside sustentacular cells that ensure biomechanical stability for sound signal transduction.
Cochlea-on-a-chip
Cochlear microfluidic platforms demonstrate superior microenvironmental regulation through dynamic modulation of cellular milieus—a critical capability absent in conventional 3D inner ear organoid cultures constrained by environmental parameter rigidity. This engineering precision is indispensable for mechanistic investigations, pharmacological profiling, and pathophysiological simulations, enabling standardized experimental reproducibility unattainable in static organoid systems. Such technological advancements establish these microfluidic devices as revolutionary instruments for deciphering cochlear mechanisms and accelerating therapeutic breakthroughs in auditory medicine.

The intricate cellular crosstalk and molecular signaling networks governing cochlear biology present significant research challenges. Recent advances in inner ear microfluidic systems have revolutionized our capacity to study auditory development. These biomimetic platforms recreate the auditory sensory niche while enabling high-resolution tracking of cellular dynamics, permitting investigation of developmental mechanisms inaccessible to conventional 2D cultures. Inner ear MPS have yielded paradigm-shifting discoveries about cochlear morphogenesis and its associated biophysical regulatory systems.

Deafness modeling and gene therapy drug testing
Inner ear organoids have proven instrumental in modeling auditory deficits associated with genetic variants like Tmprss3, SLA26A4, GJB2, MYO7A, and MYO15A. However, technical constraints in scalability and standardization limit conventional organoid systems' suitability for high-throughput pharmacological screening. Hereditary hearing disorders demonstrate mutation-specific pathophysiological impacts that differ substantially across genetic loci, necessitating patient-tailored therapeutic paradigms.
Microfluidic cochlear MPS technology excels in high-content pharmacological analysis, proving particularly indispensable for developing genotype-specific interventions. Through the integration of patient-derived iPSCs, researchers can engineer MPS containing hair cell lineages harboring defined genetic lesions. These systems enable parallel assessment of multiple gene correction strategies, permitting accelerated identification of viable therapeutic candidates. Furthermore, modular MPS configurations can be designed for distinct mutation sites within a gene, enabling systematic validation of single or combinatorial genetic therapies.

Ototoxic and Hearing Protective Drug Testing
The human cochlea's intricate three-dimensional architecture and specialized microenvironment, combined with limited tissue accessibility, create substantial barriers to investigating ototoxicity and auditory preservation mechanisms in living systems. This has driven conventional pharmacological research to predominantly utilize murine models. Clinical applicability of preclinical findings remains constrained by evolutionary disparities between species in auditory system architecture, biomolecular signaling, and immune homeostasis. Inner ear microfluidic systems have surfaced as novel assessment platforms for evaluating ototoxic agents and auditory protectants. Though stem cell-derived constructs (hiPSC/hESC) currently represent nascent-stage implementations, these systems permit large-scale pharmacological screening via biomimetic reconstructions of auditory physiology under microenvironmental precision.

Blood-Labyrinth Barrier Cochlear Chip Model
The blood-labyrinth barrier (BLB) functions as an essential vascular regulator, maintaining cochlear fluid balance, protecting auditory components from blood-derived toxins, and preserving ionic equilibrium crucial for auditory processing. Despite its critical role, the BLB's functional alterations under inflammatory, ototoxic, or hereditary disease states remain inadequately understood.
Engineered cochlear models replicating BLB architecture permit novel examination of drug metabolism patterns, toxicity pathways, and treatment development approaches. These microfluidic systems are specifically designed for comprehensive pharmaceutical analysis, enabling detailed investigation of substance permeation across the BLB, including auditory-protective compounds and inner ear-damaging therapeutics.
