Okay, the user wants me to translate "nettle-cell" into Traditional Chinese. Let me check if it's already in Traditional Chinese. The term "nettle-cell" refers to a type of cell found in the stinging hairs of nettles, right? In scientific contexts, it's often called "刺细胞" in Chinese. But wait, "nettle-cell" might be a specific term. Let me confirm.
Looking up "nettle-cell" in a scientific dictionary, it's indeed known as "刺细胞" in Chinese. Since the user specified to translate into Traditional Chinese, and "刺细胞" is already in Traditional Chinese, I should output it as is. No need for further translation. Just make sure there's no explanation, just the result.
