We aimed to develop a reproducible protocol for isolating and maintaining long-term cultures of human fungiform taste papillae cells. Cells from human fungiform papillae obtained by biopsy were successfully maintained in culture for more than eight passages (12 months) without loss of viability.

Knowledge of molecular mechanisms underlying gustatory transduction has recently enjoyed significant advances, largely due to using animal models. However, the wide diversity in taste sensitivity and specificity among mammals warrants studies in human tissue. We describe a biopsy technique to collect living taste cells from the papillae on human tongue.

Generating Neurons by Reprogramming Human Dermal Fibroblast Cells

The video demonstrates the generation of neurons from adult human dermal fibroblasts (aHDFs). The aHDFs are reprogrammed using a lentiviral vector carrying genes for neuronal transcription factors and short hairpin RNAs (shRNAs). The shRNAs inhibit the expression of a neuronal transcriptional repressor, and the neuronal transcription factors activate genes to differentiate aHDFs into neurons. These reprogrammed aHDFs are cultured in an early and a late neuronal conversion medium to generate...

Fibroblast behavior underlies a spectrum of clinical entities, but they remain poorly characterized, largely due to their inherent heterogeneity. Traditional fibroblast research relies upon in vitro manipulation, masking in vivo fibroblast behavior. We describe a FACS-based protocol for the isolation of mouse skin fibroblasts that does not require cell culture.
FAQs
The interlocking interface between the dermis and epidermis increases their contact area and strengthens attachment. This organization helps the two layers function as a connected structural unit rather than as separate surfaces. When that attachment is compromised, the cutaneous barrier may become less effective, creating conditions in which inflammation and pathogen access become important research concerns.
Connective tissue provides structural support within each papilla, while capillary loops support nourishment of the overlying epidermis. Together, these components help maintain the local tissue environment required for epidermal function. In immunology and infection studies, examining this support system can help relate changes in dermal structure to impaired barrier performance or skin disease progression.
Sensory receptors contribute to tactile sensation, giving dermal papillae a function beyond mechanical attachment and epidermal support. Their presence helps researchers distinguish sensory consequences from structural or barrier-related effects when analyzing skin tissue. This distinction is useful when a condition affects the dermis and epidermis but produces several different functional outcomes.
Disruption can weaken the connection between the dermis and epidermis and reduce the effectiveness of the cutaneous barrier. A compromised barrier may permit greater pathogen access to skin tissue, while associated inflammatory responses can influence disease development and progression. Dermal papillae therefore provide a structural context for studying how tissue injury connects barrier failure with infection-related pathology.
A useful evaluation considers the papillae’s interlocking arrangement, the strength of dermal-epidermal attachment, and the presence of connective tissue, capillary loops, and sensory receptors. Researchers can then relate these structural features to epidermal nourishment, tactile function, and barrier effectiveness. This integrated view helps distinguish changes in tissue organization from broader inflammatory or infection-associated effects.
They link tissue architecture with barrier performance because their arrangement helps secure the epidermis to the dermis. When investigators study barrier disruption, dermal papillae offer a way to consider whether altered attachment or reduced structural support could contribute to pathogen access and inflammatory responses. Their relevance is therefore both anatomical and directly connected to skin disease mechanisms.
