Thyroid transcription factor-1, abbreviated TTF-1 is a transcription factor seen in lung and thyroid.[1]
| Thyroid transcription factor-1 | |
|---|---|
| Immunostain in short | |
 TTF-1 staining in lung adenocarcinoma. (WC) | |
| Normal staining pattern | nuclear staining |
| Positive | adenocarcinoma of the lung, small cell carcinoma of the lung, thyroid, hepatocellular carcinoma (cytoplasmic staining) |
| Negative | squamous cell carcinoma of the lung |
Positive staining
- Nuclear staining.
